Ison Comet to Make Close Pass of Earth

The comet was discovered using the International Scientific Optical Network's (Ison) 40 cm telescope. It is classified as "a few tens of miles across" and will be visible to the naked eye around Thanksgiving.
Right now astronomers believe Ison will pass within two million miles of Earth (EXTREMELY close in astronomical terms) in about a year. We will provide an update in the coming months with a narrower timeframe of Ison's near-miss.
