A satellite the size of a large car is hurtling towards Earth and is expected to crash down within days.
The 2.5-tonne German X-ray telescope is speeding towards Earth at about 23,000 km/h, but scientists are unsure where it will hit, the ABC reports.
Parts as large as a refrigerator door and weighing up to 400kg could hit the Earth, but scientists say most of the satellite named ROSAT will burn up as it re-enters the atmosphere.
