A new classification scheme may help us better understand planet formation — including the history of our own family of worlds.

It’s like a big, thick bubble around our solar system, made of icy, comet-like objects. Credit: NASA The spiral pattern is about 15,000 astronomical units wide, or around 1.4 trillion miles from one ...

Light gases like helium hung around in the gas-and-dust nebula that formed the solar system for only a few million years. "It's very much debated how long it took the Earth to form," Olson said.

NEW YORK — Seven planets grace the sky at the end of February in what’s known as a planetary parade, though some will be difficult to spot with the naked eye. These planetary hangouts happen when ...

The Oort Cloud is the name given to a theorized group of potentially trillions of icy objects on the edge of our solar system. But while it has been accepted as a theory for over 70 years ...
