697402 Ao
(697402) Ao, provisional designation , is an outer main-belt asteroid. It was discovered on 23 January 2017, by the citizen science project Come On! Impacting ASteroids (COIAS) using archival data from the Subaru Telescope, which was first reported to the Minor Planet Center in February 2024. Orbit Ao is an Outer Main-belt Asteroid in a heliocentric orbit with a semi-major axis of about 3.2 AU in a relatively circular orbit with an eccentricity of 0.09 and an inclination of about 9 degrees. It orbits the Sun every 5.8 years. Discovery and naming The first observation of Ao was on 25 March 2006 by Mt. Lemmon Survey. The asteroid was also observed and reported in later years. It was only in late 2016 and 2017 that it was observed for multiple nights in a single opposition, which is how the Minor Planet Center determines the discovery opposition. These observations made using the Subaru Telescope were not reported until February 2024, through the web-based citizen science pro ...

Main-belt
The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies called asteroids or minor planets. The identified objects are of many sizes, but much smaller than planets, and, on average, are about one million kilometers (or six hundred thousand miles) apart. This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System. The asteroid belt is the smallest and innermost circumstellar disc in the Solar System. Classes of small Solar System bodies in other regions are the near-Earth objects, the centaurs, the Kuiper belt objects, the scattered disc objects, the sednoids, and the Oort cloud objects. About 60% of the main belt mass is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid be ...

Orbital Eccentricity
In astrodynamics, the orbital eccentricity of an astronomical object is a dimensionless parameter that determines the amount by which its orbit around another body deviates from a perfect circle. A value of 0 is a circular orbit, values between 0 and 1 form an elliptic orbit, 1 is a parabolic escape orbit (or capture orbit), and greater than 1 is a hyperbola. The term derives its name from the parameters of conic sections, as every Kepler orbit is a conic section. It is normally used for the isolated two-body problem, but extensions exist for objects following a rosette orbit through the Galaxy. Definition In a two-body problem with inverse-square-law force, every orbit is a Kepler orbit. The eccentricity of this Kepler orbit is a non-negative number that defines its shape. The eccentricity may take the following values: * Circular orbit: * Elliptic orbit: * Parabolic trajectory: * Hyperbolic trajectory: The eccentricity is given by e = \sqrt where ...

Asteroid In Love
is a Japanese Yonkoma, four-panel manga series by Quro, serialized in Houbunsha's seinen manga, ''seinen'' manga magazine ''Manga Time Kirara Carat'' from January 2017 to June 2024. It has been collected in six ''tankōbon'' volumes. An anime television series adaptation by Doga Kobo aired from January to March 2020. Plot During her childhood, a girl named Mira Konohata befriends Ao Manaka, who she believes is a boy, and makes a promise with Ao to discover an asteroid. Upon entering high school, Mira joins the earth sciences club, a merger of the school's astronomy and geology clubs, and reunites with Ao, who she discovers is actually a girl. Alongside their fellow club members, Mira and Ao take part in various astronomical and geological activities in the hopes of one day discovering an asteroid.

Anime
is a Traditional animation, hand-drawn and computer animation, computer-generated animation originating from Japan. Outside Japan and in English, ''anime'' refers specifically to animation produced in Japan. However, , in Japan and in Japanese, describes all animated works, regardless of style or origin. Many works of animation with a Anime-influenced animation, similar style to Japanese animation are also produced outside Japan. Video games sometimes also feature themes and art styles that are sometimes labelled as anime. The earliest commercial Japanese animation dates to 1917. A characteristic art style emerged in the 1960s with the works of cartoonist Osamu Tezuka and spread in the following decades, developing a large domestic audience. Anime is distributed theatrically, through television broadcasts, Original video animation, directly to home media, and Original net animation, over the Internet. In addition to original works, anime are often adaptations of Japanese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manga
are comics or graphic novels originating from Japan. Most manga conform to a style developed in Japan in the late 19th century, and the form has a long history in earlier Japanese art. The term is used in Japan to refer to both comics and cartooning. Outside of Japan, the word is typically used to refer to comics originally published in Japan. In Japan, people of all ages and walks of life read manga. The medium includes works in a broad range of genres: action, adventure, business and commerce, comedy, detective, drama, historical, horror, mystery, romance, science fiction and fantasy, erotica ( and ), sports and games, and suspense, among others. Many manga are translated into other languages. Since the 1950s, manga has become an increasingly major part of the Japanese publishing industry. By 1995, the manga market in Japan was valued at (), with annual sales of 1.9billion manga books and manga magazines (also known as manga anthologies) in Japan (equivale ...

Inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body. It is expressed as the angle between a reference plane and the orbital plane or axis of direction of the orbiting object. For a satellite orbiting the Earth directly above the Equator, the plane of the satellite's orbit is the same as the Earth's equatorial plane, and the satellite's orbital inclination is 0°. The general case for a circular orbit is that it is tilted, spending half an orbit over the northern hemisphere and half over the southern. If the orbit swung between 20° north latitude and 20° south latitude, then its orbital inclination would be 20°. Orbits The inclination is one of the six orbital elements describing the shape and orientation of a celestial orbit. It is the angle between the orbital plane and the plane of reference, normally stated in degrees. For a satellite orbiting a planet, the plane of reference is usually the plane containing the planet's equator. For pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-major Axis
In geometry, the major axis of an ellipse is its longest diameter: a line segment that runs through the center and both foci, with ends at the two most widely separated points of the perimeter. The semi-major axis (major semiaxis) is the longest semidiameter or one half of the major axis, and thus runs from the centre, through a focus, and to the perimeter. The semi-minor axis (minor semiaxis) of an ellipse or hyperbola is a line segment that is at right angles with the semi-major axis and has one end at the center of the conic section. For the special case of a circle, the lengths of the semi-axes are both equal to the radius of the circle. The length of the semi-major axis of an ellipse is related to the semi-minor axis's length through the eccentricity and the semi-latus rectum \ell, as follows: The semi-major axis of a hyperbola is, depending on the convention, plus or minus one half of the distance between the two branches. Thus it is the distance from the ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julian Day
The Julian day is a continuous count of days from the beginning of the Julian period; it is used primarily by astronomers, and in software for easily calculating elapsed days between two events (e.g., food production date and sell by date). The Julian period is a chronological interval of 7980 years, derived from three multi-year cycles: the Indiction, Solar, and Lunar cycles. The last year that was simultaneously the beginning of all three cycles was , so that is year 1 of the current Julian period, making AD year of that Period. The next Julian Period begins in the year AD 3268. Historians used the period to identify Julian calendar years within which an event occurred when no such year was given in the historical record, or when the year given by previous historians was incorrect. The Julian day number (JDN) has the same epoch as the Julian period, but counts the number of days since the epoch rather than the number of years since then. Specifically, ...
