Essential Questions and Answers on Vast Thin Disk of Satellites in "MISCELLANEOUS»UNFILED"
What is VTDS?
VTDS (Vast Thin Disk of Satellites) is a collection of billions of tiny, icy bodies that orbit the Sun beyond the orbit of Neptune. These objects are thought to be the remnants of the primordial solar nebula from which the planets formed.
How big is VTDS?
VTDS is about 15 billion kilometers in diameter and 0.1 billion kilometers thick. It extends from about 10 to 500 billion kilometers from the Sun.
How many objects are in VTDS?
VTDS is estimated to contain trillions of objects, ranging in size from a few meters to hundreds of kilometers in diameter.
What are VTDS objects made of?
VTDS objects are mostly made of ice, with some rock and dust. The ices include water ice, methane ice, and ammonia ice.
How do VTDS objects move?
VTDS objects orbit the Sun in a disk-like shape, with most of them orbiting in nearly circular paths. Their orbits are controlled by the gravity of the Sun, Neptune, and other planets.
Why are VTDS objects so interesting?
VTDS objects are of interest to astronomers because they are thought to be relics of the early solar system. They may provide clues about the formation and evolution of the planets and the solar system as a whole.
Final Words: The Vast Thin Disk of Satellites is a fascinating region of the Milky Way that provides unique insights into galaxy formation and evolution. Its vast expanse and composition offer valuable information for astronomers seeking to understand the structure and dynamics of our cosmic neighborhood.
