... Although they all formed from similar material, it is a mystery why the planets closest to the Sun Mercury, Venus and Earth are so different. Astronomers hope to learn more about how they were created by studying asteroids, which are pieces of rock that were surplus to requirements in planet building.

This process is thought to occur in circumstellar disks of gas and dust around young stars on rather short timescales : infrared surveys show that the number of low mass stars with disks drops dramatically for stars older than 10 Myr, suggesting that in order to form large solids before the disk disperses, the growth process has to take place within a few million years. ...

Top] [Prev] [Next] . The large number of disks surrounding young forming stars as well as the recent detections of massive extra-solar planets suggest that planetary formation commonly occurs. The next challenge is clearly the detection of Earth-like planets. From the ground their detection is likely to remain problematic due to the very low masses and luminosities inferred, whereas space observations enable these detections. ...
