Close approach of asteroid 2013 GM3 with the Earth in April 2026

Sorry, this entry is only available in Russian.

Siberian fireball

Fireball observed today in Siberia, is not related to the other flyby, what expected today. Asteroid 2012 DA14 larger than this meteoroid in ten times. Collision with the Earth is EXCLUDED.

In late of this week will be held radar observation of asteroid 2012 TC4

According to Lance Benner, a member of the radar team, later of this week should be held radar imaging of recently discovered asteroid 2012 TC4, which will be pass on October 12 at distance about 97,000 km from the Earth. Currently required astrometric and photometric support observations by ground-based telescopes.

Another close approach on October 12

A few hours the Earth will pass close to discovered two days ago an asteroid 2012 TV, and now we expect even closer flyby of asteroid, discovered by an US survey Pan-STARRS. Object that has the temporary designation P104imJ was discovered on October 4. Within 8 days, on October 12 (4:45 UT), the asteroid will flyby at least 97,000 km from the Earth. According to preliminary data, the size of the object can be from 15 to 30 meters.

Very interesting the lead time for discovering of such objects. Amateur, 40-cm telescope, was discovered larger object in just 2 days before it’s close approach, while powerful, professional 1.8-meter telescope, discovered the object of more than a week before it’s close approach to our planet.

Next close approach of an asteroid is on 7th October

Tomorrow, at 19:03 Moscow time, a Near-Earth asteroid will make a close approach. The asteroid was discovered at the privately owned Tenagra Observatory less than 24 hours ago. Currently, the object is still being confirmed by the Minor Planet Center and has been given temporary designation TCT501. The asteroid should pass at 256 500 km from Earth, which is inside the lunar orbit. Weather permitting, tomorrow we will conduct photometric observations of this object. This asteroid is estimated to be 25-50 meters in diameter.
