Planetary scientists have long wondered why Mars is only about half the size and one-tenth the mass of Earth.
Scientists have discovered the first Trojan asteroid.
For decades, researchers have been puzzled over the origins of Saturnâ€™s baby moons, which, according to many models, are so small that they should have been blown to pieces long ago by impacts with asteroids and comets.
The Purple Mountain Observatory and the Department of Astronomy, Nanjing University, in Nanjing China-Research, cooperating with the Albert Einstein institute, in Hannover, Germany, put forward a model of the planar co-orbital circular restricted three-body problem, gave the equations of motion, a set of approximation formulas, and an approximate semi-analytical solution.
The study shows that the comets were probably captured 600 million years after the formation of the solar system, during the Late Heavy Bombardment
University of Arizona scientists have uncovered a curious case of missing asteroids.
Saturn's moon Hyperion -- Hyperion is a moon of Saturn discovered by Bond and Lassell in 1848. It is the largest highly irregular (non-spherical) body in the solar system (Proteus is quite a bit larger but is almost spherical). It seems likely that Hyperion is a fragment of a larger body that was broken by a large impact in the distant past. The largest crater on its surface is approximately 120 kilometers in diameter and 10 kilometers deep. Like most of Saturn's moons, Hyperion's low...
