- Not a Near Earth Object
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
Groebe is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Groebe as potentially hazardous because its orbit does not bring it close to Earth.
Groebe orbits the sun every 1,850 days (5.07 years), coming as close as 2.82 AU and reaching as far as 3.08 AU from the sun. Based on its brightness and the way it reflects light, Groebe is probably between 2.707 to 6.054 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.
No Close Approaches
Groebe's orbit is 1.84 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
Groebe's orbit is determined by observations dating back to Sept. 27, 1990. It was last officially observed on June 8, 2023. The IAU Minor Planet Center records 1,037 observations used to determine its orbit.
Accessibility and Exploration
This asteroid is not considered a viable target for human exploration by the NHATS study.Similar Objects
