Key Facts


Mallada is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Mallada as potentially hazardous because its orbit does not bring it close to Earth.

Mallada orbits the sun every 1,670 days (4.57 years), coming as close as 2.55 AU and reaching as far as 2.96 AU from the sun. Mallada is about 13.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

No Close Approaches

Mallada's orbit is 1.56 AU from Earth's orbit at its closest point. This means that there is an extremely 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

Mallada's orbit is determined by observations dating back to Nov. 16, 1979. It was last officially observed on March 10, 2021. The IAU Minor Planet Center records 2,166 observations used to determine its orbit.

Accessibility and Exploration

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