- Not a Potentially Hazardous Object
- See orbit simulation
Overview
2020 HB40 is a very small asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2020 HB40 as potentially hazardous because its orbit does not bring it close to Earth.
2020 HB40 orbits the sun every 1,210 days (3.31 years), coming as close as 1.79 AU and reaching as far as 2.65 AU from the sun. Based on its brightness and the way it reflects light, 2020 HB40 is probably between 0.320 to 0.715 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.
No Close Approaches
2020 HB40's orbit is 0.78 AU from Earth's orbit at its closest point. This means that there is a very 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 HB40's orbit is determined by observations dating back to April 16, 2020. It was last officially observed on April 26, 2020. The IAU Minor Planet Center records 24 observations used to determine its orbit.
