53435 (1999 VM40)

Key Facts

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

Overview

53435 (1999 VM40) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1999 VM40 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.

1999 VM40 orbits the sun every 1,280 days (3.50 years), coming as close as 1.19 AU and reaching as far as 3.43 AU from the sun. Based on its brightness and the way it reflects light, 1999 VM40 is probably between 2.996 to 6.699 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

The rotation of 1999 VM40 has been observed. It completes a rotation on its axis every 5.19 hours.

1999 VM40's spectral type None (Tholen) / S (SMASSII) indicates that it is likely to contain and .

No Close Approaches

1999 VM40's orbit is 0.20 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 VM40's orbit is determined by observations dating back to Aug. 13, 1974. It was last officially observed on June 4, 2022. The IAU Minor Planet Center records 2,728 observations used to determine its orbit.
