311999 (2007 NS2)

Key Facts

• Categorized as a Mars-crossing Asteroid
• Comparable in size to the Golden Gate Bridge
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

311999 (2007 NS2) is a small asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2007 NS2 as potentially hazardous because its orbit does not bring it close to Earth.

2007 NS2 orbits the sun every 687 days (1.88 years), coming as close as 1.44 AU and reaching as far as 1.61 AU from the sun. Based on its brightness and the way it reflects light, 2007 NS2 is probably between 0.615 to 1.374 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.

No Close Approaches

2007 NS2's orbit is 0.46 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

2007 NS2's orbit is determined by observations dating back to Dec. 14, 1998. It was last officially observed on July 24, 2022. The IAU Minor Planet Center records 276 observations used to determine its orbit.

Accessibility and Exploration

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