In our solar system, Mercury, Venus, Earth, and Mars have period ratios of about 2.6, 1.6, and 1.9, respectively. Overall, the study showed that our solar system fits reasonably well into the team ...

A tiny comet fragment from the outer edges of the solar system was found on Earth — inside a meteorite. Scientists discovered a tiny blob of carbon about the width of a human hair inside a rocky ...

New studies offer a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs. The findings reveal the distribution of ices ...

According to NASA, the heliopause is often considered to be the outer border of the solar system. However, in its news release, NASA did not say that the Voyager 1 had left the solar system.

The outer reaches of our Solar System continue to reveal a complex dynamical environment where the interplay of gravitational forces shapes the orbits of a myriad of distant bodies. Research in ...
