Key Facts

Overview

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

Syukumeguri orbits the sun every 2,000 days (5.48 years), coming as close as 2.71 AU and reaching as far as 3.51 AU from the sun. Syukumeguri is about 19.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Denver.

No Close Approaches

Syukumeguri's orbit is 1.71 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

Syukumeguri's orbit is determined by observations dating back to Jan. 25, 1984. It was last officially observed on June 7, 2023. The IAU Minor Planet Center records 3,194 observations used to determine its orbit.

Accessibility and Exploration

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