All About 2020 BX12
Editorials News | Mar-29-2020
2020 BX12 is a sub-kilometer binary asteroid, classified as a near-Earth asteroid and potentially hazardous object of the Apollo group. It was discovered on 27 January 2020, by the Asteroid Terrestrial-impact Last Alert System survey at the Mauna Loa Observatory in Hawaii. The asteroid was discovered during its close approach to Earth from a nominal distance of 11.35 lunar distances, or approximately 4.36 million km (2.71 million mi). radar observations of the asteroid were carried out, revealing a small natural satellite orbiting 360 m (1,180 ft) from the primary body. The discovery of the satellite was announced by the Arecibo Observatory on 10 February 2020.
2020 BX12 was discovered on 27 January 2020, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey at the Mauna Loa Observatory in Hawaii. The ATLAS survey was designed for detecting near-Earth asteroids on approach to Earth, particularly those that may be considered potentially hazardous under circumstances where they can approach Earth from close distances. 2020 BX12 was identified by a team of astronomers consisting of Larry Denneau, John Tonry, Aren Heinze, and Henry Weiland, who were chiefly involved in the ATLAS project. The asteroid was discovered during its approach to Earth, and was at nominal distance of about 0.11 AU (16,000,000 km; 10,000,000 mi) from the planet. At the time of discovery, 2020 BX12 was located in the constellation of Puppis at an apparent magnitude of 17.6.[a]
The discovery of 2020 BX12 was subsequently reported to the Minor Planet Center's near-Earth object confirmation page (NEOCP), where a preliminary orbit was calculated from additional observations conducted at multiple observatories. Follow-up observations of 2020 BX12 spanned three days since its discovery, and the asteroid was formally announced in a Minor Planet Electronic Circular issued by the Minor Planet Center on 30 January 2020.
