A newly discovered asteroid about the size of a house will zip safely by Earth on Wednesday (April 15), passing just inside the orbit of the moon.
The asteroid 2020 GH2 will pass Earth at a range of about 223,000 miles (359,000 kilometers). The average distance from the Earth to the moon is about 239,000 miles (385,000 km).
On April 15, an asteroid the size of a house, 2020 GH2, is expected to pass by our planet from within the orbit of the Moon.
According to NASA's Asteroid Watch program, asteroid 2020 GH2 is about between 43 and 70 feet (13-70 meters) wide, or about the size of a detached house. It was first discovered on Saturday (April 11) and is being tracked by astronomers at several observatories, including the Catalina Sky Survey at Mount Lemmon in Arizona, according to the Minor Planet Center at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts.

Asteroid 2020 GH2 poses no impact risk to Earth during its flyby. While flying inside the moon's orbit sounds like a close shave by an asteroid, there's actually a lot of room.
In a March 31 video shared on Twitter by NASA's Asteroid Watch group, Kelly Fast of the agency's Planetary Defense Office demonstrated just how much space is out there. She used a tennis ball as the moon and a basketball as the Earth, placing them 25 feet (7 meters) apart in a hallway — the scale distance between the Earth and moon. At that scale, a huge asteroid like the one that doomed the dinosaurs would be the size of a grain of salt, Fast said.
