Mera

Key Facts

• Categorized as a Amor-class Asteroid
• Comparable in size to Mount Everest
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

Mera is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Mera 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.

Mera orbits the sun every 770 days (2.11 years), coming as close as 1.12 AU and reaching as far as 2.17 AU from the sun. Based on its brightness and the way it reflects light, Mera is probably between 1.376 to 3.076 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

The rotation of Mera has been observed. It completes a rotation on its axis every 3.19 hours.

No Close Approaches

Mera's orbit is 0.29 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

Mera's orbit is determined by observations dating back to May 11, 1985. It was last officially observed on July 22, 2023. The IAU Minor Planet Center records 1,339 observations used to determine its orbit.

Accessibility and Exploration

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