Key Facts

Overview

13047 (1990 RJ5) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1990 RJ5 as potentially hazardous because its orbit does not bring it close to Earth.

1990 RJ5 orbits the sun every 1,470 days (4.02 years), coming as close as 2.16 AU and reaching as far as 2.90 AU from the sun. 1990 RJ5 is about 3.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

No Close Approaches

1990 RJ5's orbit is 1.18 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

1990 RJ5's orbit is determined by observations dating back to Sept. 15, 1990. It was last officially observed on Feb. 2, 2023. The IAU Minor Planet Center records 2,455 observations used to determine its orbit.

Accessibility and Exploration

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