Key Facts

Overview

2018 MV4 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 MV4 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2018 MV4 orbits the sun every 511 days (1.40 years), coming as close as 0.95 AU and reaching as far as 1.55 AU from the sun. Based on its brightness and the way it reflects light, 2018 MV4 is probably between 0.179 to 0.400 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

No Close Approaches

2018 MV4'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

2018 MV4's orbit is determined by observations dating back to June 3, 2015. It was last officially observed on May 29, 2022. The IAU Minor Planet Center records 72 observations used to determine its orbit.

Accessibility and Exploration

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