Skyscraper-sized asteroid to pass within 1.7m miles of Earth on Friday
An asteroid as big as a skyscraper will pass within 1.7m miles (2.7mkm) of Earth on Friday.
Don’t worry: there’s no chance of it hitting us since it will miss our planet by seven times the distance from the Earth to the moon.
Nasa’s Center for Near Earth Object Studies estimates the space rock is between 690 and 1,575 feet (210 and 480 meters) across. That means the asteroid could be similar in size to New York City’s Empire State Building or Chicago’s Willis Tower.
Discovered in 2008, the asteroid is designated as 2008 OS7. It won’t be back our way again until 2032, but that will be a much more distant encounter, staying 45m miles away.
The harmless flyby is one of several encounters this week. Three much smaller asteroids also will harmlessly buzz the Earth on Friday, no more than tens of yards across, with another two on Saturday. On Sunday, an asteroid roughly half the size of 2008 0S7 will swing by, staying 4.5m miles away.

Robot Dog Controlled By Someone Not On Earth For The First Time In History
For the first time in the history of robot dogs and space travel, a four-legged robodog has been controlled by a human outside of the Earth’s atmosphere. Only robots with wheels have been controlled remotely from space before now. The “Surface Avatar” test carried out in January saw European Space Agency (ESA) astronaut Marcus Wandt control several different robotic systems on Earth from the International Space Station (ISS), part of a project that eventually aims to allow human commanders to control robots on other worlds like the Moon or Mars while in orbit around them.Wandt controlled a dog-like robot named Bert created by the German Aerospace Center (DLR).
