On Feb 15th, a 150ft/50m asteroid will come within 17,000 miles of Earth. Any amateur astronomers will be able to see it with a telescope, but it will move a whole degree through the sky (the size of 2 full moons) every minute.. so it will be tough.
The moon is @ 250k miles from us. So this will thread close to the orbit of the Int’l Space Station. It will be under 10% as far from Earth as the Moon.
