Renzia

Key Facts

• Categorized as a Mars-crossing Asteroid
• Comparable in size to the city of Cleveland, Ohio
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

Renzia is a large asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Renzia as potentially hazardous because its orbit does not bring it close to Earth.

Renzia orbits the sun every 1,240 days (3.39 years), coming as close as 1.60 AU and reaching as far as 2.93 AU from the sun. Based on its brightness and the way it reflects light, Renzia is probably between 10.582 to 23.661 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Cleveland, Ohio.

The rotation of Renzia has been observed. It completes a rotation on its axis every 7.89 hours.

Renzia's spectral type None (Tholen) / S (SMASSII) indicates that it is likely to contain magnesium silicate and iron silicate.

No Close Approaches

Renzia's orbit is 0.59 AU from Earth's orbit at its closest point. This means that there is an 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

Renzia's orbit is determined by observations dating back to Oct. 6, 1931. It was last officially observed on Jan. 22, 2021. The IAU Minor Planet Center records 3,275 observations used to determine its orbit.

Scientists have been able to determine this object's shape.
