Protoplanet
Protoplaneter er store planetære embryoner, som bliver dannet gennem samlingen af stof, der er i kredsløb omkring unge stjerner. En protoplanet bliver til en planet, hvis den samler nok masse til at opnå hydrostatisk ligevægt.

Protoplanetary discs observed with SPHERE.jpg

These three planetary discs have been observed with the SPHERE instrument, mounted on ESO’s Very Large Telescope. The observations were made in order to shed light on the enigmatic evolution of fledgling planetary systems. The central parts of the images appear dark because SPHERE blocks out the light from the brilliant central stars to reveal the much fainter structures surrounding them.
