Discovered on January 27, 2020 by the ATLAS survey, 2020 BX12 is a round object at least 165 m (541 feet) in diameter rotating approximately once every 2.8 hours or less.  The satellite may have formed as a result of rotational fission or mass ejection of the primary body, since 2020 BX12 along with other binary near-Earth asteroids have been observed to have rapid rotation periods and spheroidal shapes. As it approaches perihelion, 2020 BX12 moves above the ecliptic and comes closer to the Sun than Venus, whereas at aphelion, 2020 BX12 moves below the ecliptic and recedes from the Sun farther out than the orbit of Mars.  During its close approach to Earth, the asteroid approached Earth at a rate of 25.3 km/s (57,000 mph) and its apparent visual brightness peaked around magnitude 15.7, which is too faint to be seen with the naked eye. It was discovered on 27 January 2020, by the Asteroid Terrestrial-impact Last Alert System survey at the Mauna Loa Observatory.  Excluding delay-Doppler effects on the satellite's brightness in radar images, the satellite's albedo may be slightly higher than that of the primary (~0.3), likely around 0.36 based on a generic magnitude-to-diameter conversion using an absolute magnitude of 22.5 and a diameter of 70 m., From radar images taken on 5 February 2020, the separation distance between the satellite and the primary body is estimated to be about 360 m (1,180 ft), or 4.4 times the radius of the 2020 BX12 primary. , In Arecibo delay-Doppler radar observations from 4 January to 5 January 2020, 2020 BX12 was resolved at a resolution of 7.5 meters per pixel, allowing for direct measurements of the asteroid's physical properties. Based on the observations, the scientists discovered that 2020 BX12 is a binary asteroid, with a smaller rock orbiting the larger rock. Samsung Galaxy S20 FE पर मिल रही 9,000 रुपये की छूट, लेकिन...

However, uncertainties remain in measurements of the satellite's rotation period, thus an upper limit to its period was placed at 49 hours.. , The asteroid's minimum orbital intersection distance (MOID) from Earth is approximately 0.002 AU (0.30 million km; 0.19 million mi), or about 0.78 lunar distances. The larger rock is likely at least 540 feet (165 meters) across, and the smaller one is about 230 feet (70 m) wide, according to the observations gathered by Arecibo. The asteroid was discovered during its approach to Earth of 0.02915 AU (4.361 million km; 11.34 LD). The last Earth encounter by 2020 BX12 from a closer distance was on 1 February 1931, when the asteroid approached Earth from a distance of 0.009 AU (1.3 million km; 0.84 million mi), or 3.5 lunar distances. During its close approach to Earth, the asteroid approached Earth at a rate of 25.3 km/s (57,000 mph) and its apparent visual brightness peaked around magnitude 15.7, which is too faint to be seen with the naked eye.

Potentially Hazardous Asteroid That Buzzed Earth Was Travelling With Its Own Moon. radar observations of the asteroid were carried out, revealing a natural satellite orbiting 360 m (1,180 ft) from the primary body. According to the observations made by Arecibo Observatory on February 5, the two bodies were 360 meters apart from each other. “Due to projection effects, uncertainties remain on the rotation periods, and a shorter mutual orbital period of 15-16 hours has not yet been ruled out.”, “The secondary appears brighter than the primary body in the radar images, which is common for radar images of binaries.”, “The horizontal axis in delay-Doppler images shows, in fact, the echo power per Doppler-shifted frequency, or in other words the surface area that has a specific radial velocity relative to the observer.”, “This makes objects that rotate slower appear narrower in delay-Doppler images than objects that rotate faster.”, “Because the secondary body rotates much slower than the primary, its echo power is distributed to fewer Doppler frequency bins than the echo power from the primary body, making the amount of echo power per pixel appear more intense.”, © 2011-2020. The MOID of the larger asteroid was 302,000kms from Earth which meant it could come closer to our planet than our Moon. The calculations also show that it will pass Mars in June this year. , On 12 February 2020, a team of astronomers identified 2020 BX12 in several precovery images taken by the Pan-STARRS 1 survey, with the earliest images dating back to 5 January 2014. , The satellite of 2020 BX12 was discovered in Arecibo radar observations conducted by a team of astronomers consisting of Luisa Zambrano-Marín along with other members of the Planetary Radar Science Group. It’s 19.5 miles long and orbited by Dactyl, only 4,600 feet across.  Although 2020 BX12 has a sufficiently long observation arc for its orbit to be accurately determined, the asteroid has not yet been issued a permanent minor planet number by the Minor Planet Center.  After follow up observations confirming the object, it was then given the provisional designation 2020 BX12 by the Minor Planet Center on 30 January 2020.  2020 BX12 appears to have a nearly spheroidal shape, which is commonly observed in other near-Earth objects such as 2005 YU55 and 101955 Bennu. However, the … , Upon discovery, the asteroid was given the temporary internal designation A10jUnf.  Radar images show that 2020 BX12 is at least 165 m (541 ft) in diameter, implying a geometric albedo or reflectivity of 0.30 given its absolute magnitude of 20.6. Radar images from the Arecibo Observatory have shown that the asteroid by the name of 2020 BX12 that passed Earth earlier this month was a binary asteroid.  At the time of discovery, 2020 BX12 was located in the constellation of Puppis at an apparent magnitude of 17.6. As it approached Earth space, asteroid 2020 BX12 was under close observation.  However, another possible orbital period of 15–16 hours (0.63–0.67 days) has not been yet been ruled out, due to projection effects of radar images. Sci-News.com. , 2020 BX12 orbits the Sun at an average distance of approximately 1.60 astronomical units (0.239×10^9 km; 0.149×10^9 mi), taking 2.02 years to complete one full orbit.  Having such a small Earth MOID, 2020 BX12 is considered a potentially hazardous asteroid (PHA) by the Minor Planet Center, under the definition that PHAs have Earth MOIDs less than 0.05 AU and absolute magnitudes under 22. The orbit of 2020 BX12 is highly eccentric and inclined to the ecliptic plane: it has an orbital eccentricity of 0.757 and inclination of 40 degrees, with its orbit extending from 0.76 AU at perihelion to 2.44 AU at aphelion. [b], The February 2020 encounter by 2020 BX12 provided an opportunity for radar observatories to study the asteroid's characteristics in detail.

Discovered on January 27, 2020 by the ATLAS survey, 2020 BX12 is a round object at least 165 m (541 feet) in diameter rotating approximately once every 2.8 hours or less. This object fits the definition of a potentially hazardous asteroid due to its size and minimum orbit intersection distance of 302,000 km (188,000 miles) from the Earth. When the instrument … Dr. Luisa Fernanda Zambrano-Marín and her colleagues at the Arecibo Observatory observed 2020 BX12 on February 4 and 5, 2020. The secondary body was first observed on February 4 by the observatory located in Puerto Rico.  The next two Earth encounters by 2020 BX12 will occur in February 2022 and 2024, with approach distances of 0.18 AU and 0.34 AU, respectively.  Radar observations of 2020 BX12 were conducted on 4 February 2020 by a team of astronomers led by Luisa Zambrano-Marín. The calculations also show that it will pass Mars in June this year. While this means it could conceivably come closer to the Earth than the Moon, the asteroid poses no danger at this time and is currently receding from Earth. But, now that it is moving away from Earth and doesn't classify as dangerous. The larger asteroid was discovered by Asteroid Terrestrial-impact Last Alert System (ATLAS) survey on January 27. NASA has classified the 2020 BX12 under Apollo meaning “Near-Earth asteroid orbits which cross the Earth's orbit similar to that of 1862 Apollo (a > 1.0 au; q < 1.017 au).” According to the agencies data, the 2020 BX12 was first observed in 2014 and last observed on February 7.
On 3 February 2020 at 18:56 UTC, 2020 BX 12 passed 0.02915 AU (4.36 million km; 2.71 million mi), or 11.35 lunar distances, from Earth. For the latest tech news and reviews, follow Gadgets 360 on Twitter, Facebook, and Google News.
