HD 98800

This is a young quadruple system of orange stars, two orbiting narrow double-stars. Around the smaller pair B are two dust belts, which could be appropriate for forming planets. The outer belt with a distance of 5.9 AU to the pair probably consists of large chunks like asteroids and comets. The inner one with 1.5 - 2 AU distance in contrast is likely made of fine grains. Between these two there is a chance that an already finished planet could sit.
