48864 (1998 HK43)

Key Facts

• Categorized as a Mars-crossing Asteroid
• Comparable in size to Mount Everest (2.34 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

48864 (1998 HK43) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 1998 HK43 as potentially hazardous because its orbit does not bring it close to Earth.

1998 HK43 orbits the sun every 1,240 days (3.39 years), coming as close as 1.61 AU and reaching as far as 2.90 AU from the sun. 1998 HK43 is about 2.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

The rotation of 1998 HK43 has been observed. It completes a rotation on its axis every 4.07 hours.

No Close Approaches

1998 HK43's orbit is 0.61 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

1998 HK43's orbit is determined by observations dating back to Sept. 26, 1995. It was last officially observed on Nov. 21, 2022. The IAU Minor Planet Center records 1,472 observations used to determine its orbit.
