When an orbiting spacecraft runs out of fuel, it keeps staying in orbit. It does not "tumble back to earth" unless it is close enough that the atmosphere is thick enough to slow it down further.
Hubble is about 500 km elevation, and it's expected to take about 30 years for its orbit to decay, from the last time it was reboosted. For Beresheet it would be much longer.
In this case, perigee is 668 km from the earth, which is in low-earth orbit, but it's apogee is 69020 km away, or high earth orbit - https://heavens-above.com/orbit.aspx?satid=44049&lat=0&lng=0... .
