1999 JZ10

Key Facts

• Categorized as a Apollo-class Asteroid
• Comparable in size to a school bus or smaller
• Classified as a Near Earth Asteroid (NEA)
• Classified as a Potentially Hazardous Asteroid (PHA)
• See orbit simulation

Overview

1999 JZ10 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1999 JZ10 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1999 JZ10 orbits the sun every 545 days (1.49 years), coming as close as 0.69 AU and reaching as far as 1.92 AU from the sun. Based on its brightness and the way it reflects light, 1999 JZ10 is probably between 0.096 to 0.214 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

No Close Approaches

1999 JZ10's orbit is 0.04 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

1999 JZ10's orbit is determined by observations dating back to May 14, 1999. It was last officially observed on June 3, 1999. The IAU Minor Planet Center records 56 observations used to determine its orbit.

Accessibility and Exploration

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