Is it......circling?
on the moon... right?

NASA explains how it would alert the public of an apocalyptic asteroid strike

‘First, the party members who detected the threat would share their observations across the IAWN network to verify their findings and assess the danger.
‘Once all parties agree that Earth should brace for impact, NASA would send out an alert.
“I don’t have a red phone on my desk or anything,” Johnson said.’
I thought we were doomed to global warming what difference does this make other than more money?

Phooey.
What are they going to do? Nuke it?
SID from the TV show UFO?

Most likely about 2 hours before impact...
Stars, intense gravity, collisions, etc. produce natural light in the radio spectrum that is captured by radio telescopes.
Small asteroids and comets produce no radio waves unless they are being heated by an atmosphere or a star.
Are we going to build giant radar transmitters and flood Earth's local neighborhood with radar waves 24-7 to detect silent almost invisible space rocks and ice boulders that might strike Earth?
That sounds like a hugely expensive and complex project.
