Key Facts

Overview

7409 (1990 BS) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1990 BS as potentially hazardous because its orbit does not bring it close to Earth.

1990 BS orbits the sun every 1,340 days (3.67 years), coming as close as 1.87 AU and reaching as far as 2.89 AU from the sun. 1990 BS is about 4.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of 1990 BS has been observed. It completes a rotation on its axis every 31.61 hours.

No Close Approaches

1990 BS's orbit is 0.88 AU from Earth's orbit at its closest point. This means that there is a very 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

1990 BS's orbit is determined by observations dating back to Dec. 19, 1974. It was last officially observed on June 8, 2023. The IAU Minor Planet Center records 3,251 observations used to determine its orbit.

Accessibility and Exploration

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