To reproduce the orbits and masses of the terrestrial planets (analogs) of the solar system, most studies scrutinize simulations for success as a batch. However, there is insufficient discussion in ...

It's largely agreed that the moon was created around 4.5 billion years ago when a protoplanet collided with early molten ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. New research suggests that most of the solar system's inner rocky planets once orbited the sun in ...

What: Astronomers using JWST and ALMA have captured the earliest known stage of planet formation around the protostar HOPS-315 in the Orion Molecular Cloud. Guest: Dr ...

New work from Carnegie’s Alan Boss offers a potential solution to a longstanding problem in the prevailing theory of how rocky planets formed in our own solar system, as well as in others. The snag he ...

Recent scientific discoveries have unearthed evidence of a cataclysmically destroyed planet, fragments of which contributed ...

A new SwRI-led paper highlights the scientific progress made in understanding the evolution of terrestrial planets, including the effects of late large impacts on pre-existing modes of tectonics. For ...

Best chance of finding liquid water, and even life on other planets, is to look for the absence of carbon dioxide in their atmospheres. Scientists at MIT, the University of Birmingham, and elsewhere ...

Late-stage planetary collisions reshaped Earth and its neighboring planets, delivering water, altering their atmospheres, and influencing their tectonics. New findings suggest these violent impacts ...

A planet's year length depends on its distance from the Sun. Planets closer to the Sun have shorter years. A planet's rotation speed is unrelated to its year length. Planets' orbital speeds vary ...
