If the Spitzer Space Telescope is slowly drifting away from us, but sharing the Earths orbit around the Sun, won it eventually crash into us?
The Spitzer Space Telescope will drift all the way around Earth’s orbit and back to the Earth about 60 years after it is launched. Many of the instruments will no longer be functioning by then because the liquid helium will have run out. Spitzer is so small that when it hits the Earth’s atmosphere, it will burn up before it reaches the surface of the Earth. There is no danger to worry about.
