Yukitsuna is a core member of the Maria family (506), a large intermediate belt family of stony asteroids. Alternatively, it has also been assigned to the stony Eunomia family (502), one of the most prominent families in the intermediate main belt with more than 5,000 members.

It orbits the Sun in the central main-belt at a distance of 2.2–2.9 AU once every 4 years and 1 month (1,489 days; semi-major axis of 2.55 AU). Its orbit has an eccentricity of 0.16 and an inclination of 16° with respect to the ecliptic.

The asteroid was first observed as 1943 UF at Heidelberg Observatory in October 1943. The body's observation arc begins as 1974 FQ₁ at Crimea–Nauchnij in March 1974, more than 17 years prior to its official discovery observation at Yakiimo.

Zone of Avoidance (is the area of the sky that is obscured by the Milky Way. The Zone of Avoidance was originally called the Zone of Few Nebulae in an 1878 paper by English astronomer Richard Proctor that referred to the distribution of "nebulae" in John Herschel's General Catalogue of Nebulae. When viewing space from Earth, the attenuation, interstellar dust and stars in the plane of the Milky Way (the galactic plane) obstruct the view of around 20% of the extragalactic sky at visible wavelengths. As a result, optical galaxy catalogues are usually incomplete close to the galactic plane. Many projects have attempted to bridge the gap in knowledge caused by the Zone of Avoidance. The dust and gas in the Milky Way cause extinction at optical wavelengths, and foreground stars can be confused with background galaxies. However, the effect of extinction drops at longer wavelengths, such as the infrared, and the Milky Way is effectively transparent at radio wavelengths. Surveys in the infrared, such as IRAS and 2MASS, have given a more complete picture of the extragalactic sky. Two very large nearby galaxies, Maffei 1 and Maffei 2, were discovered in the Zone of Avoidance by Paolo Maffei by their infrared emission in 1968. Even so, approximately 10% of the sky remains difficult to survey as extragalactic objects can be confused with stars in the Milky Way. Projects to survey the Zone of Avoidance at radio wavelengths, particularly using the 21 cm spin-flip emission line of neutral atomic hydrogen (known in astronomical parlance as HI), have detected many galaxies that could not be detected in the infrared. Examples of galaxies detected from their HI emission include Dwingeloo 1 and Dwingeloo 2, discovered in 1994 and 1996, respectively)

The Ant Nebula, whose technical name is Mz3, resembles the head and thorax of an ant when observed with ground-based telescopes. The new Hubble image, with 10 times the resolution revealing 100 times more detail, shows the "ant's" body as a pair of fiery lobes protruding from a dying, Sun- like star. The Ant Nebula is located between 3,000 and 6,000 light years from Earth in the southern constellation Norma.

Boötes Void (is an approximately spherical region of space found in the vicinity of the constellation Boötes, containing very few galaxies, hence its name. It is enormous, with a radius of 62 megaparsecs. Its center is located at approximately right ascension 14h 50m and declination 46°. At nearly 330 million light-years in diameter (approximately 0.27% of the diameter of the observable Universe), or nearly 236,000 Mpc3 in volume, the Boötes Void is one of the largest known voids in the Universe, and is referred to as a supervoid. Its discovery was reported by Robert Kirshner et al. (1981) as part of a survey of galactic redshifts. The centre of the Boötes Void is approximately 700 million light-years from Earth. Other astronomers soon discovered that the void contains a few galaxies. In 1987, J. Moody, Robert P. Kirshner, G. MacAlpine, and S. Gregory published their findings of eight galaxies in the void. M. Strauss and John Huchra announced the discovery of three more galaxies in 1988, and Greg Aldering, G. Bothun, Robert P. Kirshner, and Ron Marzke announced the discovery of fifteen galaxies in 1989. By 1997, the Boötes Void was known to contain 60 galaxies in a space that would usually roughly have 2000. According to astronomer Greg Aldering, the scale of the void is such that "If the Milky Way had been in the center of the Boötes Void, we wouldn't have known there were other galaxies until the 1960s." The Hercules Supercluster forms part of the near edge of the void)

Nicolaus Copernicus (19 February 1473 – 24 May 1543) was a Renaissance polymath, active as a mathematician, astronomer, and Catholic canon, who formulated a model of the universe that placed the Sun rather than Earth at its center. In all likelihood, Copernicus developed his model independently of Aristarchus of Samos, an ancient Greek astronomer who had formulated such a model some eighteen centuries earlier

Dark Shark Nebula (is a beautiful dark nebula in the constellation of Cepheus which resembles our favorite ocean predator. It is comprised of dark dust which is faintly illuminated by the surrounding stars and is thus very difficult to image, requiring exceptionally dark skies and moonless nights. The Dark Shark is about 650 light years away and you can see a distant galaxy PGC 67671 through the dust in the top right of the frame. You can also note 2 small blue reflection nebula vdB 149 and vdB 150)

The Egg Nebula (also known as RAFGL 2688 and CRL 2688) is a bipolar protoplanetary nebula approximately 3,000 light-years away from Earth. Its peculiar properties were first described in 1975 using data from the 11 µm survey obtained with sounding rocket by Air Force Geophysical Laboratory (AFGL) in 1971 to 1974. (Previously, the object was catalogued by Fritz Zwicky as a pair of galaxies.)

The Egg Nebula's defining feature is the series of bright arcs and circles surrounding the central star. A dense layer of gas and dusts enshrouds the central star, blocking its direct light from our view. However, the light from the central star penetrates the thinner regions of this dusty enclosure, illuminating the outer layers of gas to create the arcs seen in this resplendent image (Hubble Site). Spectra of the starlight scattered by the dust reveal that the central star has a spectral type of F5.^[4] The photosphere of an F5 star is about 900 K hotter than that of the Sun, but it is still not hot enough to have begun ionizing the nebula. Therefore the Egg Nebula is at a slightly earlier evolutionary stage than the Westbrook Nebula whose spectral type B0 central star has just recently begun to ionize the nebula.

The dusty enclosure around the central star is very likely a disc.

Friede (was a fictional spacecraft designed by Hermann Oberth and was featured in the 1929 silent movie Woman in the Moon. The Friede was, at the time, the most realistic depiction of space travel, having multiple stages, liquid fuel, and other details. Having the Friede submerged in water before launch was not replicated for actual Moon launches, however. In the film, the Friede carried five passengers and a stowaway. The Friede was designed to travel to the Moon in search of gold, and the crew successfully found gold on the Moon. One crew member, Turner, tried to hijack the ship. Turner was shot and killed, but the bullets damaged the oxygen tanks, and the crew came to the grim realization that one of them must remain. Two people stayed behind on the Moon, which was depicted as having a breathable atmosphere. During the 1930s, all schematics and blueprints related to the Friede were confiscated by the Gestapo and were lost during the war. Hermann Oberth had trouble creating a flying miniature for the premiere of the movie)

This is about the movie titled "Gravity". Let me know if I need to change it.

Gravity is a 2013 science fiction thriller film directed by Alfonso Cuarón, who also co-wrote, co-edited, and produced the film. It stars Sandra Bullock and George Clooney as American astronauts who are stranded in space after the mid-orbit destruction of their Space Shuttle, and attempt to return to Earth.

Cuarón wrote the screenplay with his son Jonás and attempted to develop the film at Universal Pictures. Later, the distribution rights were acquired by Warner Bros. Pictures. David Heyman, who previously worked with Cuarón on Harry Potter and the Prisoner of Azkaban (2004), produced the film with him. Gravity was produced entirely in the United Kingdom, where British visual effects company Framestore spent more than three years creating most of the film's visual effects, which involve over 80 of its 91 minutes.

Gravity opened the 70th Venice International Film Festival on August 28, 2013, and had its North American premiere three days later at the Telluride Film Festival. Upon its release, Gravity was met with widespread critical acclaim, with praise for its direction and visuals. Considered one of the best films of 2013, it appeared on numerous critics' year-end lists, and was selected by the American Film Institute in their annual Movies of the Year list. The film became the eighth highest-grossing film of 2013 with a worldwide gross of over $723 million, against a production budget of around $100 million.

The film earned accolades from numerous critics and guilds. At the 86th Academy Awards, Gravity received ten nominations, including Best Actress for Bullock and Best Picture, and won seven awards, including Best Director, Best Original Score, Best Cinematography, and Best Visual Effects. The film was also awarded six BAFTA Awards, including Outstanding British Film and Best Director, the Golden Globe Award for Best Director, seven Critics' Choice Movie Awards, the 2013 Ray Bradbury Award, and the 2014 Hugo Award for Best Dramatic Presentation.

Comment: Cool movie ... with two fantastic actors. I loved it.
