Key Facts

Overview

13742 (1998 SX22) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1998 SX22 as potentially hazardous because its orbit does not bring it close to Earth.

1998 SX22 orbits the sun every 1,670 days (4.57 years), coming as close as 2.28 AU and reaching as far as 3.22 AU from the sun. Based on its brightness and the way it reflects light, 1998 SX22 is probably between 3.152 to 7.048 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

No Close Approaches

1998 SX22's orbit is 1.28 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

1998 SX22's orbit is determined by observations dating back to Feb. 14, 1991. It was last officially observed on April 14, 2023. The IAU Minor Planet Center records 1,924 observations used to determine its orbit.

Accessibility and Exploration

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