All asteroids with an Earth Minimum Orbit Intersection Distance (MOID) of 0.05 au or less and an absolute magnitude (H) of 22.0 or less are considered PHAs. Astronomers expect the asteroid from the depths of space to skim past the planet tomorrow, March 7 around 7.53am TDB. At its minimum distance, NASA expects the asteroid to approach Earth within 0.09 AU, or 1,346,380 km. Amateurs might be able to catch it with smaller telescopes.
Asteroid 2017 VR12 was first discovered on November 10 2017 by the The Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) observatory in Hawaii. VR12 last fellow past Earth on June 17 2010 and will next visit the planet on march 19 in the year 2026. “About once a year, an automobile-sized asteroid hits Earth’s atmosphere, creates an impressive fireball, and burns up before reaching the surface. Only once every few million years, an object large enough to threaten Earth’s civilisation comes along.” NASA informed. The next asteroid, asteroid 2018 BK7, will zoom by on Friday March 9, nearing the planet within 3,955,201 km.
