Key Facts

Overview

2008 SC is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2008 SC as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2008 SC orbits the sun every 416 days (1.14 years), coming as close as 0.33 AU and reaching as far as 1.86 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2008 SC is probably between 0.121 to 0.272 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

No Close Approaches

2008 SC's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is a 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

2008 SC's orbit is determined by observations dating back to Sept. 19, 2008. It was last officially observed on Sept. 24, 2008. The IAU Minor Planet Center records 18 observations used to determine its orbit.

Accessibility and Exploration

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