Part of the show Meteorites, Satellites and Avoiding Asteroids

Question

Treasure in Essex asked:

I look out of my window and see something that appears to be a satellite. It rises in the sky through the night. It appears to flash. Is it a satellite?

Answer

It's more likely to be a planet. When planets travel through a large depth of atmosphere, they appear to twinkle. Sometimes they twinkle very bright colours. You will eventually lose sight of it as it's orbiting around the sun.
