19091 (1978 XX)

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the San Francisco Bay (6.93 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

19091 (1978 XX) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1978 XX as potentially hazardous because its orbit does not bring it close to Earth.

1978 XX orbits the sun every 1,590 days (4.35 years), coming as close as 2.36 AU and reaching as far as 2.98 AU from the sun. 1978 XX is about 6.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of 1978 XX has been observed. It completes a rotation on its axis every 4.22 hours.

No Close Approaches

1978 XX's orbit is 1.40 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

1978 XX's orbit is determined by observations dating back to May 2, 1976. It was last officially observed on May 15, 2023. The IAU Minor Planet Center records 2,832 observations used to determine its orbit.
