Шаблон:Short description Шаблон:Infobox planet
Amphitrite (minor planet designation: 29 Amphitrite) is one of the largest S-type asteroids, approximately Шаблон:Convert in diameter, and probably fifth largest after Eunomia, Juno, Iris and Herculina.
Discovery
Amphitrite was discovered by Albert Marth on 1 March 1854, at the private South Villa Observatory, in Regent's Park, London. It was Marth's only asteroid discovery. Its name was chosen by George Bishop, the owner of the observatory, who named it after Amphitrite, a sea goddess in Greek mythology.[1]
Characteristics
Amphitrite's orbit is less eccentric and inclined than those of its larger cousins; indeed, it is the most circular of any asteroid discovered up to that point. As a consequence, it never becomes as bright as Iris or Hebe, especially as it is much further from the Sun than those asteroids. It can reach magnitudes of around +8.6 at a favorable opposition, but usually is around the binocular limit of +9.5.
In 2007, James Baer and Steven R. Chesley estimated Amphitrite to have a mass of 1.9Шаблон:E kg.[2] A more recent estimate by Baer suggests it has a mass of 1.18Шаблон:E kg.[3]
A satellite of the asteroid is suspected to exist, based on lightcurve data collected by Edward F. Tedesco.[4][5] In 1988 a search for satellites or dust orbiting this asteroid was performed using the UH88 telescope at the Mauna Kea Observatories, but neither were found.[6]
