Since the formation of the Solar System, the orbits of the planets have evolved and changed over time. While one of the most prominent ideas in the last few decades is planetary migrations and the ...

The massive object flew through the solar system at a velocity of about 6km per second, coming within 20 astronomical units of the sun and shaping the orbits of the gas giant planets into what we ...

Their orbits tend to be less than 10 days long; by comparison, Mercury in our own solar system circles the sun every 88 days.

Our solar system orbits the galactic centre at a distance of some 26,000 light years, but to find stars and planets created under similar conditions to our own, astronomers would first need to ...

NASA artist’s conception of a brown dwarf (main) and stock image of the planets in the solar system (inset). An object between 2 and 50 times the mass of Jupiter may have flown through our ...

Despite common assumptions, the disk of our Solar System is warped, and the planets travel around the Sun in slightly eccentric (or oblong) orbits. Scientists now think that a mysterious object ...

The solar system orbits around the center of the Milky Way — our galaxy — but even within the frame of the solar system, the sun is not exactly static because of the gravitational interaction ...
