A ringed 70 Vir B presides over the hot and airless terrain of a
hypothetical moon. While it is not known if 70 Vir B has rings, it is certainly
possible. Saturn is the planet best-known for its rings of ice and stone, but all the
other jovian planets in our solar system (Jupiter, Uranus and Neptune) have rings as well.
70 Vir B's rings would have no ice in them due to is proximity to its sun. Such
rings would likely be less than 100 million years old and could have been formed from the
shattered remnants of an asteroid that wondered too close to this giant planet.
70 Vir B's eccentric orbit would increase the likelihood of its encountering
other objects in orbit around 70 Virginis.
About 78
light years from the Earth astronomers believe that there is a
large planet orbiting 70 Virginis, a type G5V star (similar to our own sun). Designated 70 Vir B, this planet is believed to have
over six times the mass of the planet Jupiter and orbits around its sun in an eccentric
orbit once every 116 days. 70 Vir B's average distance from its sun is about the
same as that of the planet Mercury from our own sun.
