Key Facts

Overview

141079 (2001 XS30) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2001 XS30 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2001 XS30 orbits the sun every 459 days (1.26 years), coming as close as 0.20 AU and reaching as far as 2.13 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2001 XS30 is probably between 0.774 to 1.730 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.

2001 XS30's spectral type None (Tholen) / Xc (SMASSII) indicates that it is likely to contain iron, nickel, cobalt, and platinum.

No Close Approaches

2001 XS30's orbit is 0.30 AU from Earth's orbit at its closest point. This means that there is an 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

2001 XS30's orbit is determined by observations dating back to Nov. 16, 1998. It was last officially observed on Feb. 10, 2021. The IAU Minor Planet Center records 532 observations used to determine its orbit.

Accessibility and Exploration

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