Astronomers propose a new hypothetical planet, Planet Y, beyond Neptune, based on observed orbital anomalies in the Kuiper ...

Our solar system's planets aren't weird after all. Exoplanets have tilted orbits, too Elizabeth Howell Thu, November 30, 2023 at 2:00 PM UTC 3 min read ...

In this activity, you’ll learn how to make scale drawings of solar system orbits, learn about a team of women engineers who launched a satellite mission to orbit Mars, and then plot your own path to ...

The Solar System is a fascinating place, with each planet orbiting the Sun at its own unique distance. But how far apart are these planets, and how do they travel through space? Uncover the true ...

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 ...

The strange orbits of some objects in the farthest reaches of our solar system, hypothesised by some astronomers to be shaped by an unknown ninth planet, can instead be explained by the combined ...

The astronomers–from the United States, Australia, Belgium and the United Kingdom–are searching the nearest 1,200 stars for planets similar to those in our solar system, particularly Jupiter ...

In a 2009 paper in the journal Nature, Laskar and co-author Mickael Gastineau ran numerical models of some 2500 orbits using current knowledge of our solar system’s initial orbital parameters.
