The number of planets that orbit the sun depends on what you mean by “planet,” and that’s not so easy to define ...

An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit before shoving four of the solar system's planets onto a different course.

15, 2025 — New observational data and simulation models have confirmed a new type of planet unlike anything found in the Solar System ... that it detected no global dipole magnetic fields ...

Currently, the sun is spitting out solar flares like there's no tomorrow thanks to the ongoing solar maximum — the peak in the sun's roughly 11-year cycle of activity — so there will be no ...

Our solar system was doing just fine without humanity for 99.995% of its lifetime Our Solar System is quite “young”, at least as far as solar systems go. Using radiometric dating, scientists were able ...

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 ...

In the early evening, look to the southwest and you'll see Venus (the brightest object in the sky after the Sun and Moon) and ...

The solar system consists of stars, the Sun, 8 planets, dozens of moons, millions of asteroids, comets, and meteoroids. It orbits the centre of the Milky Way galaxy at about 515,000 mph.

Mars and the Earth’s moon have localized regional magnetic fields at different places across their surfaces, but no global field ... refer to the small rocky and metallic bodies of the inner solar ...

The visitors in 1% of simulations dove straight into the solar system, travelling past Uranus' orbit and some even grazed Mercury's path and they ranged from two to 50 times the mass of Jupiter.
