Lightcurve analysis indicates that Eugenia's pole most likely points towards ecliptic coordinates (β, λ) = (-30°, 124°) with a 10° uncertainty,[4] which gives it an axial tilt of 117°. The mean anomoly is 126.65097, is the angular distance of the planet from the perihelion or aphelion. Because most asteroids, including Take your favorite fandoms with you and never miss a beat.

with a 304 mm SCT equipped with a 3.3 focal reducer, WAT910 HX B/W video camera CFHT time-lapse image of Eugenia and Petit-Prince, showing five stages in the moon's orbit. Because of its size, Eugenia is a fairly bright object at mag 11.2 and is easily discernible from the target star as seen on the two images below. The orbital inclination, the angle at which Eugenia orbits in relation to the orbital plane is 6.60558 degrees. It is famous because it is one of the first asteroids to be found to have a moon orbiting it. Orbital characteristics. In 1998, astronomers at the Canada-France-Hawaii Telescope on Mauna Kea, Hawaii, discovered a small moon orbiting Eugenia. This is a non-deconvolved summation of 16 raw images of 15-s duration each, obtained on 1 November 1998 UT . by the Franco-German amateur astronomer Hermann Goldschmidt. asteroid – a highly porous jumble of fairly loose rocks.

Unfortunately, of the six other observers that had planned to also participate, all were clouded out of the event. 5a and 5b illustrate each step of the analysis. Eugenia was discovered in 1857 by Hermann Goldschmidt. This name refers to Empress Eugenia's son, the Prince Imperial. The first-discovered asteroid from the ground, which was also the first confirmed asteroidal moon after Dactyl, was detected around the large main-belt asteroid (45) Eugenia on November 1, 1998, by a team led by William Merline using the 3.6-meter Canada-France-Hawaii Telescope (CFHT) at Mauna Kea Observatory in Hawaii. It is the angle along the orbit of a planet or other Solar System object as measured from the ascending node (analogous to right ascension and longitude) Ref:Hawaii. It is famous because it is one of the first asteroids to be found to have a moon orbiting it. 45 Eugenia eller 1941 BN är en asteroid som ligger i asteroidbältet.Den är känd för att vara en av de första asteroiderna där man upptäckte och bekräftade en måne.
There's no register feature and no need to give an email address if you don't need to. A name is preferred even if its a random made up one by yourself. October 6, 1999 An international team of astronomers has discovered a moon orbiting the asteroid (45)Eugenia. The little moon, named Petit-Prince travels around Eugenia in a 5-day circular Eugenia was discovered in 1857 by Hermann Goldschmidt. All messages will be reviewed before being displayed. Required fields are marked *. The moon is much smaller than Eugenia, about 13 km in diameter, and takes five days to complete an orbit around it. exist for this low density: either the asteroid is made mostly of ice, or Its orbit takes 4.49 years to travel round the Sun. Combining mass and size determines the asteroid's density, which in this case gives a surprising result - Eugenia is found to have a density only 20% greater than water. The orbital eccentricity is 0.0841645, it is the degree at which Eugenia orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit. Its takes 5.699 hours to do a full rotation period. The Longitude of Ascending Node of the object is 147.60017 degrees. The pictures, taken with the Canada-France-Hawaii Telescope (CFHT) on Mauna Kea, Hawaii, are the first images of an asteroidal satellite taken from Earth.

A second, smaller (estimated diameter of 6 km) satellite that orbits closer to Eugenia than Petit-Prince has since been discovered and provisionally named S/2004 (45) 1. It is famous because it is one of the first asteroids to be found to have a moon orbiting it. son of Empress Eugenia. The 'flare' around them is an imaging artifact. Time stamp data for each of the images is shown at the bottom of each frame. Video It is also the second known triple asteroid, after 87 Sylvia. The ascending node is the point in which the object passes north. In November 1998, astronomers at the Canada-France-Hawaii Telescope on Mauna Kea, Hawaii, discovered a small moon orbiting Eugenia.

The Argument of Perihelion is 87.7962. Petit-Prince orbiting Eugenia I was able to record the event The more popular view, though, is that it is a rubble-pile moon to be discovered by a ground-based telescope. A higher absolute magnitude means that the object is faint whereas a very low number means it is very bright.

Current Position. From Virginia Beach , 45 Eugenia is not observable – it will reach its highest point in the sky during daytime and is no higher than 14° above the horizon at dawn. However, the discoverers also intended an allusion to the children's novella The Little Prince by Antoine de Saint-Exupéry, which is about a young prince who lives on an asteroid. The descending node is the southern.
45 Eugenia is a main-belt asteroid around which, in 1998, a satellite was discovered – the first such discovery using a ground-based telescope. in the novel lives on an asteroid. Light curve data and occultation event timing extraction was completed 45 Eugenia is a main-belt asteroid around which, in 1998, This was the first time an asteroidal moon had been discovered by a ground-based telescope. Previously, the only The orbit of the moon yields the approximately 08:12:45 +/- 2 sec UT (01:12:45 PDT). They tend to be an irregular shaped but Ceres asteroid is known to be spherical in shape but because it doesn't clear its path round the Sun, it is only a dwarf planet. These images were extracted from integrated video taken as the asteroid approached the target star and after the predicted event. Predicted event time was The name is especially apt since The Little Prince 45 Eugenia is a big Main belt asteroid. telescope. Take your favorite fandoms with you and never miss a beat.
