Key Facts

Overview

58980 (1998 RG47) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 1998 RG47 as potentially hazardous because its orbit does not bring it close to Earth.

1998 RG47 orbits the sun every 1,200 days (3.29 years), coming as close as 1.63 AU and reaching as far as 2.80 AU from the sun. Based on its brightness and the way it reflects light, 1998 RG47 is probably between 2.026 to 4.529 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

1998 RG47's orbit is 0.62 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 RG47's orbit is determined by observations dating back to Dec. 16, 1995. It was last officially observed on April 16, 2023. The IAU Minor Planet Center records 1,633 observations used to determine its orbit.

Accessibility and Exploration

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