Key Facts

Overview

Rinjani is a mid-sized asteroid orbiting between Mars and Jupiter within the inner portion of the asteroid belt. NASA JPL has not classified Rinjani as potentially hazardous because its orbit does not bring it close to Earth.

Rinjani orbits the sun every 974 days (2.67 years), coming as close as 1.80 AU and reaching as far as 2.04 AU from the sun. Based on its brightness and the way it reflects light, Rinjani is probably between 1.376 to 3.076 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

No Close Approaches

Rinjani's orbit is 0.81 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

Rinjani's orbit is determined by observations dating back to Oct. 7, 1977. It was last officially observed on Sept. 2, 2022. The IAU Minor Planet Center records 1,306 observations used to determine its orbit.

Accessibility and Exploration

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