The solar system is composed of the sun, eight major planets, five dwarf planets, over a hundred moons, and countless comets and asteroids. In this article, we will be looking at 21 mind-blowing facts ...

Jupiter's rapid early growth dramatically reshaped our solar system, scientists now reveal. Its immense gravity acted as a cosmic divider, separating materials and influencing where planets formed.

The Solar System is a weird place filled with incredible physics and geological oddities that often break down in human terms. The way we learn the order of the planets is the classroom version of ...

Our solar system is a smashing success. A new study suggests that from its earliest period — even before the last of its nebular gas had been consumed — Earth’s solar system and its planets looked ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf ...

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

Scientists say a nearby red dwarf star hosts a planetary lineup that looks like a mirror image of our own solar system, with rocky worlds bookending a pair of gas-rich planets. Around the star LHS ...
