The asteroid 2017 NB7 will fly past the Earth on August 6

The newly discovered Amur-type asteroid, designated 2017 NB7, will pass next to the Earth on August 6 at a safe distance of 6.8 Earth-to-Moon, or 2.6 million kilometers. This near-Earth object will sweep alongside our planet at approximately 10:43 UTC, moving relative to it at a speed of 5.98 kilometers per second.

The asteroid 2017 NB7 was discovered on July 1, 2017, using the Mount Lemmon Survey (MLS) sky survey, using the 1.52-meter Cassegrain reflector located at Mount Lemmon Observatory, USA. The MLS survey is one of the most fruitful sky surveys when it comes to discovering new near-Earth objects. With the help of this review, more than 50,000 minor planets have been discovered so far.

Astronomers have found out that the diameter of the asteroid 2017 NB7 is from 36 to 110 meters, and the absolute magnitude is 23.6. The semimajor axis of the asteroid’s orbit around the Sun is estimated by specialists at 1.6 astronomical units, and the orbital period of the cosmic stone is about two years.

In addition to the asteroid 2017 NB7 on August 6, another cosmic stone will pass by the Earth. The 2017 OJ7 asteroid from 41 to 130 meters in diameter will pass our planet at a much greater distance, 30 Earth-Moon distances, or 11.5 million kilometers.

Currently, 1803 potentially dangerous asteroid are discovered, but neither of them orbit passes through our planet. Potentially dangerous is an asteroid with a diameter of more than 100 meters, capable of approaching the Earth at a distance of less than 19.5 distances from Earth to the Moon.
