NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) spacecraft has a Ben-Ru, a 1,614-foot (492 m) wide asteroid that you can use.
OSIRIS-REx arrived after Bennu (formerly 1999 RQ36) on December 3, 2018.
At 2:43 p.m. EST (7:43 GMT) on December 31, the spacecraft successfully entered the one-mile (1.75 km) orbit around the asteroid.
This is a comfortable distance.
It’s a bit different.
“During this phase, it’s not a matter of collecting data,” said the OSIRIS-REx team.
“We use these‘ OpNav ’images to monitor the spacecraft’s close orbit around the asteroid.”
These two images of Bennu were captured on January 17, 2019.
The images show the southern hemisphere of the asteroid.
The second boulder is about 165 feet (50 m) across.
