Asteroid diversity points to a "snow globe" solar system by The Watcher on January 31, 2014, Jupiter's migration through the solar system has swept asteroids out of stable orbits, sending them careening into one another. As the gas giant planets migrated, they stirred the contents of the solar system. Objects from as close to the Sun as Mercury, and as far out as Neptune, all collected in the main asteroid belt, leading to the diverse composition we see today. Credit: David A. Aguilar (CfA)
A planet four times the size of Earth may be skirting the edges of the solar system beyond Pluto, according to new research. Too distant to be easily spotted by Earth-based telescopes, the unseen planet could be gravitationally tugging on small icy objects past Neptune, helping explain the mystery of those objects' peculiar orbits. The claim comes from Rodney Gomes, a noted astronomer at the National Observatory of Brazil in Rio de Janeiro.
Understanding the size of Earth in comparison to the rest of our solar system -- an amazing illustration to visualize the size and scale of our world!
