2021 RK133

Key Facts

• Categorized as a Centaur-class Asteroid
• Comparable in size to Mount Everest
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

2021 RK133 is a mid-sized asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2021 RK133 as potentially hazardous because its orbit does not bring it close to Earth.

2021 RK133 orbits the sun every 10,500 days (28.75 years), coming as close as 3.10 AU and reaching as far as 15.68 AU from the sun. Based on its brightness and the way it reflects light, 2021 RK133 is probably between 1.447 to 3.236 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

2021 RK133's orbit is 2.15 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

2021 RK133's orbit is determined by observations dating back to Sept. 7, 2021. It was last officially observed on Jan. 4, 2022. The IAU Minor Planet Center records 40 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
