A European satellite is expected to fall to Earth due to the planet's gravitational pull in the next two days but scientists are not certain of the drop point.

The European satellite was responsible for mapping Earth's gravitational field in exquisite detail. The satellite named Gravity Field and Steady-State Ocean Circulation Explorer or GOCE was launched in 2009 had an ion engine that allowed it to remain in a low orbit 160 miles above Earth. However, it ran out of fuel last month and has been dropping 2.5 miles per day ever since.

Scientists expect that it will be pulled in by the Earth's gravity and crash into the planet anytime in the next two days. However, the exact time and location of the drop point has not been determined yet though scientists confirmed that by the time this happens, the satellite will be in fragments. The largest fragment could weigh as much as 200 pounds.

"It's rather hard to predict where the spacecraft will re-enter and impact," NY Times quoted Rune Floberghagen, the mission manager for the European Space Agency's GOCE as saying. "Concretely our best engineering prediction is now for a re-entry on Sunday, with a possibility for it slipping into early Monday."

Floberghagen is hopeful that as the satellite approaches the planet, scientists will be able to determine the exact time of the impact. However, because the satellite is on a pole-to-pole orbit it  could drop almost anywhere in the globe. According to the manager, about 15 to 20 square yards of Earth's surface might be at risk because of the satellite. Though the chances of any fragment of the satellite hitting anyone are miniscule, though not zero.
