Models of planetary formation suggest that giant extrasolar planets detected very near their stars formed at greater distances and migrated inward as a result of gravitational interactions with remnants of the circumstellar disks from which they accumulated.

Until now, it has been generally accepted that a meteor constitutes a time capsule — a relic of the early creation of the solar system that has fallen to Earth, allowing us to delve into the distant past by looking at the composition of the essentially unchanged material that formed the basis of planetary formation.

Guilloteau's team carried out the first ever direct measurements of the relatively large grains of dust in the Flying Saucer — measuring approximately one millimeter across — located around 15 billion kilometers from the star and found that they had settled to a low temperature of -447 degrees Fahrenheit -LRB--266 degrees Celsius)-- only 7 degrees above absolute zero and 15 degrees lower than what was expected, a huge discrepancy in the field of planetary formation models.
