Asteroid longer than 4 blue whales to fly past Earth

A large asteroid that is a minimum of four times the size of a blue whale (17.5 male giraffes) is set to pass by Earth on April Fool's Day, according to NASA's asteroid tracker.

Designated 2007 FF1, this asteroid has an estimated size ranging between 120 meters to 260 meters. The maximum length of a blue whale, the largest animal species thought to ever exist on Earth, is thought to be just under 30 meters. If looking for a non-cetacean comparison, the Great Pyramid of Giza in Egypt is just 130 meters in height.

Traveling at a speed of around 12.83 kilometers per second, the massive space rock is set to pass the planet at a distance of around 7.4 million kilometers. For comparison, the Moon orbits the Earth at a distance of around 384,000 kilometers, so it may not seem close. However, on a cosmic scale, this is closer than one might think, and NASA has even classified it as a Potentially Hazardous Asteroid (PHA).

This itself makes sense considering what could happen should 2007 FF1 actually hit us.
