PIX4583617: Illustration of a triple system of asteroids - Triple system of asteroids -Artwork - Artist's view of two small asteroids (Romulus and Remus) orbiting asteroid 87 Sylvia. Sylvia is about 380 km long and is one of the largest members of the asteroid belt. Two small asteroids are orbiting a larger one known since 1866 as 87 Sylvia. Sylvia is measuring 380 x 260 x 230 km; its moons are considerably smaller, orbiting in nearly circular orbits and in the same plane and direction. The closest and newly discovered moonlet, orbiting about 710 km from Sylvia, is Remus, a body only 7 km across and circling Sylvia every 33 hours. The second, Romulus, orbits at about 1360 km in 87.6 hours and measures about 18 km across. The asteroid 87 Sylvia is one of the largest known from the asteroid main belt, and is located about 3.5 times further away from the Sun than the Earth, between the orbits of Mars and Jupiter / Bridgeman Images
