A large asteroid that scientists only discovered this month will make a relatively close approach to Earth on Saturday, astronomers say, providing one of the best opportunities in years to gather data about a passing space rock.
The asteroid, estimated to be about 1,300 feet in diameter, will shoot past the planet at 22 miles per second at around 1 p.m. on Halloween afternoon. Known as 2015 TB145, it will come within about 300,000 miles of Earth, farther away than the moon but relatively close by cosmic measures.
