House-Sized Asteroid to Fly By Earth Within One Lunar Distance on June 6

Asteroid 2017 KQ27, which is about the size of the object that hit Chelyabinsk in February 2013, is about to give Earth a close shave on Tuesday, June 6. The space rock will miss our planet at a distance of approximately 384,000 kilometers, what is one lunar distance (LD).

Discovered in late May 2017, the near-Earth object (NEO) 2017 KQ27 has an absolute magnitude of 25.7 and a diameter between 14 and 45 meters. It will pass by Earth at about 15:00 UTC with a velocity of 10.7 km/s.

No other future close approaches to Earth of this asteroid are expected by astronomers, however, this space rock is slated to fly by Jupiter at a relatively large distance of 1.8 astronomical units (AU), or 270 million kilometers on September 26, 2072.

Besides 2017 KQ27, one other asteroid will also miss our planet on June 6. The object, designated 2017 KR27, is about 70 meters in diameter and will fly by Earth at a safe distance of 7 LD.

Currently, there are 1,803 potentially hazardous asteroids (PHAs) detected to date. PHAs are space rocks larger than approximately 100 meters that can come closer to Earth than 19.5 LD. However, none of the known PHAs is on a collision course with our planet.
