An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit ...

Planets orbit the Sun in roughly circular paths, and moons orbit around planets. Asteroids and comets move in paths which are more oval in shape. The Sun’s gravity holds all of these objects ...

Neptune is the furthest planet from the Sun, thirty times further than Earth. Its orbit is so huge that one year on Neptune takes almost 'one hundred and sixty five' Earth years. The James Webb ...

It actually follows its own tiny elliptical orbit around what is called the center of gravity (the barycenter) of the system, the sun and the orbiting planets. This barycenter is usually not equal ...

This occurs when the planets' positions in their elliptical orbit around the sun line make them seem like they are close in ...

The planets will appear to line up — but no more than usual. The planets in our solar system orbit the sun in more or less the same flat plane as the Earth, according to EarthSky.org, called the ...

The planets in solar do not have circular orbit around the Sun, including Earth which goes around in an elliptical orbit. A new research is now looking at what really caused this change in the ...

That puts it only slightly farther than Mars' current orbit of 1.5 AU from the sun. The simulations show that just one substellar object flyby was sufficient to alter the giant planets' trajectories.

Stargazers, prepare for the parade of planets that will take place over the next few nights in the sky. Here's what you need ...

Currently, six planets are visible in the sky in a line—and soon enough, a seventh will join them, according to the BBC. And ...

To retain vast oceans similar to Earth, the planet would have to be about 10 AU away, or roughly the distance of Saturn from the sun ... need to move inward to a close, warm orbit.
