Sub-kilometer asteroid March 2020 yes 2014 HQ 124 #FFC2E0 2014 HQ124 rep.png Radar image of 2014 HQ 124 taken by the Arecibo Observatory on 8 June 2014 NEOWISE C51 23 April 2014 2014 HQ 124 NEOAtenPHA 31 May 2020 (JD 2459000.5) 1 4.09 yr (1,495 d) 1.0712 AU 0.6303 AU 0.8508 AU 0.2591 287 days 97.870° 1.2560 ms / day 26.371° 257.56° 144.51° 0.0084 AU LD 3 on on 0.409 0.168 km 16 h > 0.291 0.216 S (assumed) 18.9 2014 HQ 124 is a sub-kilometer asteroid, classified as a near-Earth object and potentially hazardous asteroid of the Aten group, approximately 400 m ft off 2 us in diameter. It passed 3.25 lunar distances (LD) from Earth on 8 June 2014. It was discovered on 23 April 2014 by NEOWISE. It is estimated that an impact event would have had the energy equivalent of 2,000 megatons of TNT and would have created a 5 km 0 on impact crater. The news media misleadingly nicknamed it The Beast.475709720842366977 AreciboRadar For the record, we do not use nicknames to refer to asteroids. Anthropomorphizing nature is confusing and misleading. 8 June 2014 2014 HQ 124 previously passed this close to Earth in 1952 and will not again until at least 2307. Radar imaging suggests it may be a contact binary. Orbit 2014 HQ 124 orbits the Sun at a distance of 0.6–1.1 AU once every 0 years and 9 months (287 days; semi-major axis of 0.85 AU). Its orbit has an eccentricity of 0.26 and an inclination of 26° with respect to the ecliptic. 2014 close approach left|thumb|2014 HQ 124 radar images in June 2014 On 6 June 2014, the asteroid brightened to about apparent magnitude 13.7 while in the southern constellation of Horologium. Near its closest approach to Earth of 3.25 lunar distances on 8 June 2014, the asteroid crossed the celestial equator, making it a Northern Hemisphere object. It however had an elongation of about 20 degrees from the Sun, and was lost in astronomical twilight during the closest approach to Earth. The Goldstone Deep Space Network observed the asteroid later on 8 June 2014, when the asteroid was between 3.6 and 3.8 lunar distances. horizontal left 220 333 2014HQ124 orbit.png 2014_HQ124_sky-trajectory.png 2014 HQ 124 orbit showing high inclination and 2014 Earth flyby The sky trajectory of 2014 HQ 124, as seen from earth, with 12-hour motion markers left Physical characteristics According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, 2014 HQ 124 measures (0.409 0.168) kilometers in diameter and its surface has an albedo of (0.291 0.216) based on an absolute magnitude of 18.9. Radar observations at Goldstone suggest that the object is elongated and irregular in shape, with its long axis measuring at least 370 m ft off us 2. Lance Benner suspects it to be a contact binary, composed of two merged objects forming a single asteroid with a lobed shape. Photometric observations by astronomers with the Mission Accessible Near-Earth Objects Survey (MANOS) and subsequent evaluation by Brian Warners Collaborative Asteroid Lightcurve Link, determined that 2014 HQ 124 has a rotation period of at least 16 hours. While the object's spectral type is unknown, Warner assumes it to be an S-type asteroid, based on its high albedo, which is typical for stony asteroids. Related objects On average, an object about the size of 2014 HQ 124 will pass this close to Earth every few years.
