CAPE CANAVERAL, Fla. (AP) — A comet is streaking back our way after 50,000 years. The comet — a time capsule from the emerging solar system 4.5 billion years ago — came from what’s known as the Oort Cloud well beyond Pluto. While comet ZTF originated in our solar system, we can’t be sure it will stay there, Chodas said. If it gets booted out of the solar system, it will never return, he added. “In the comet business, you just wait for the next one because there are dozens of these,” Chodas said.
