A newly discovered small asteroid flew by the Earth on Saturday, August 26, approaching our planet for a distance of the order of one lunar-earth distance, or 384,000 kilometers. This near-Earth object, designated as 2017 QQ17, reached the point of closest approach to Earth at 4:23 UTC, moving relative to our planet at a speed of 21.17 kilometers per second.
The asteroid 2017 QQ17 was first seen on August 23, 2017 with the Pan-STARRS 1 Observatory (PS1) located on the Haleakala volcano on the island of Maui in the Hawaiian archipelago. The Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) is an astronomical survey that includes astronomical cameras, telescopes and data centers that allow monitoring of mobile objects in the sky in a continuous mode.
The absolute stellar magnitude of this object was 28.1, and the diameter is estimated at 4 to 14 meters. The semimajor axis of the orbit of this cosmic stone is 2.46 AU (1 astronomical unit is equal to the distance from the Earth to the Sun), and the orbital period is 3.87 years.
In addition to approaching the Earth, the asteroid accomplished the same day a rapprochement with the Moon, held at 6:58 UTC, while the asteroid was from a natural satellite of the Earth at a distance that also amounted to one lunar-earth distance. It is expected that this asteroid will pass Jupiter on November 19, 2030 at a distance of about 1.95 AU.
