147431 (2003 JA)

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

147431 (2003 JA) is a small asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2003 JA as potentially hazardous because its orbit does not bring it close to Earth.

2003 JA orbits the sun every 816 days (2.23 years), coming as close as 1.57 AU and reaching as far as 1.85 AU from the sun. Based on its brightness and the way it reflects light, 2003 JA is probably between 0.709 to 1.585 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

2003 JA's orbit is 0.58 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

2003 JA's orbit is determined by observations dating back to July 10, 2001. It was last officially observed on June 26, 2023. The IAU Minor Planet Center records 589 observations used to determine its orbit.

Accessibility and Exploration

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