About: 2020 HS7

An Entity of Type: planet, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

2020 HS7 is a very small asteroid classified as a near-Earth object of the Earth-crossing Apollo group. When it was discovered by the Pan-STARRS 2 survey on 27 April 2020, the asteroid was initially calculated to have a 10% chance of impact with Earth before being ruled out by improved orbit determinations from additional observations. Although there is now no risk of impact with Earth, it did make a close approach 42,700 kilometres (26,500 mi) from Earth on 28 April 2020, with a flyby speed of 15.6 kilometres per second (9.7 mi/s) relative to Earth. The asteroid will not make any close encounters within 1 lunar distance (380,000 km; 240,000 mi) of Earth in the next 100 years.

  • 2020 HS7 is a very small asteroid classified as a near-Earth object of the Earth-crossing Apollo group. When it was discovered by the Pan-STARRS 2 survey on 27 April 2020, the asteroid was initially calculated to have a 10% chance of impact with Earth before being ruled out by improved orbit determinations from additional observations. Although there is now no risk of impact with Earth, it did make a close approach 42,700 kilometres (26,500 mi) from Earth on 28 April 2020, with a flyby speed of 15.6 kilometres per second (9.7 mi/s) relative to Earth. The asteroid will not make any close encounters within 1 lunar distance (380,000 km; 240,000 mi) of Earth in the next 100 years. Observations by Kiso Observatory in Nagano, Japan show that the asteroid rotates extremely rapidly with a rotation period of 3 seconds, making it the fastest-rotating asteroid known as of 2022. No other near-Earth asteroid of similar size is known to have a rotation period shorter than 10 seconds, which could be attributed to the tangential component of the YORP effect accelerating their rotation far beyond this period. The asteroid exhibits a very small light curve amplitude of 0.07 magnitudes, which either implies a nearly spherical shape or a pole-on rotation during observations. (en)
  • 2020 HS7とは、2020年4月28日に地球から42,730キロメートル (26,550 mi)以内の距離で接近した地球近傍天体(NEO)として分類されている小惑星である。飛行距離は9.7マイル (15.6 km)。大きさは自動車と同程度で、最初に発見されたときは地球に影響を与える可能性が10%あったが、のちの観測により2020 HS7が地球に影響を及ぼすリスクはないことが示された。2020 HS7は地球の赤道から35,785キロメートル (22,236 mi)離れた静止軌道に最も近い衛星から1,210キロメートル (750 mi)以内の距離で接近した。 2020 HS7は、2020年4月27日にハワイのでパンスターズを使用して発見された。2055年までには月までの距離よりも近い距離まで接近することはない。 (ja)
