Asteroid 29 Amphitrite	Permalink

29 Amphitrite is one of the largest S-type asteroids, probably third in diameter after Eunomia and Juno, although Iris and Herculina are similar in size. It is probably not a fully solid body, since its density is too low for a solid silicate object and much lower than Eunomia or Juno. Its orbit is less eccentric and inclined than those of its larger cousins - being indeed the most circular of any asteroid discovered up to that point - and 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 favourable opposition, but more usually is around the binocular limit of +9.5. Read more 29 Amphitrite Click to Play \| View Details __________________
