Beta Pictoris planetary disc,artwork. Two planets are shown as insets,with an Earth-like planet above a Venus-like one. In the main picture,a protoplanetary disc has formed around the star Beta Pictoris (upper centre). Several planets have already formed,such as the gas giant at lower left. Ring-shaped empty areas are seen in the disc,formed by the passage of protoplanets in their orbits as they gather up surrounding material. At centre right,large asteroids are colliding with a rocky planet. Two comets are seen near the central Beta Pictoris star. The Beta Pictoris system is around 63 light years from Earth,in the constellation Pictor | |
