The Moons of Uranus

The Moons of Uranus May Hold the Key to Finding Missing Planets

We have an idea of what the solar system's past was like: It was violent and chaotic. However, we are still studying how violent it was. Current models suggest that at some point after their formation, the giant planets went through a phase of such extreme instability that one or even two bodies the size of Uranus or Neptune were ejected into interstellar space.

A 'lost planet' may have given Jupiter and Uranus their moons

2 giant 'super Earths' once orbited near Uranus and Neptune, messed up a bunch of moons, then vanished, new study hints

2 giant 'super Earths' once orbited near Uranus and Neptune, messed up a bunch of moons, then vanished, new study hints Our solar system may have hosted up to six giant planets in its first hundred million years, a new study suggests. The findings paint a more crowded picture of the early outer solar system than previously thought. Something doesn’t quite add up about the orbits of our solar system’s eight planets and their hundreds of moons, a new study hints.

One of our planets may be missing, and it could explain why the solar system looks the way it does

June 1, 2026 report One of our planets may be missing, and it could explain why the solar system looks the way it does Paul Arnold Author Sadie Harley Scientific Editor Robert Egan Associate Editor Our solar system has two ice giants, Uranus and Neptune, but there may have been a third. According to a new study published in the journal Icarus, this extra world might have triggered a violent planetary shuffling billions of years ago that could have disrupted some of Jupiter's and Uranus's...

Astronomers discover exoplanets with magnetic fields

Astronomers discover exoplanets with magnetic fields WASHINGTON: Based on the behaviour of winds on seven large and hot gas exoplanets, astronomers have obtained the strongest evidence to date that planets beyond our solar system possess magnetic fields, like Earth and five other planets in our solar system. The finding, based on observations by telescopes in Chile and Hawaii, deepens the understanding of exoplanets by showing that at least some share an important characteristic present in...
