Key Facts
- Categorized as a Main-belt Asteroid
- Comparable in size to the Golden Gate Bridge
- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
2020 HU77 is a small asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2020 HU77 as potentially hazardous because its orbit does not bring it close to Earth.
2020 HU77 orbits the sun every 1,680 days (4.60 years), coming as close as 2.01 AU and reaching as far as 3.51 AU from the sun. Based on its brightness and the way it reflects light, 2020 HU77 is probably between 0.402 to 0.900 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
No Close Approaches
2020 HU77's orbit is 1.09 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
Images and Observations
2020 HU77's orbit is determined by observations dating back to April 22, 2020. It was last officially observed on May 28, 2020. The IAU Minor Planet Center records 18 observations used to determine its orbit.
