An asteroid occultation occurs when a nearby asteroid briefly blocks the light from a distant star.

The Lucy mission launched in October 2021, and will fly by six Jupiter Trojans, including Eurybates and Queta, during its journey to study these still-mysterious asteroids. The Trojans, which orbit in two distinct groups, hail from the Solar System’s early days, so they function like time capsules that help scientists study that time. With their observations of Eurybates and Queta, Citizen Astronomers directly contributed to a NASA mission that may help unravel the secrets of our beginnings.
We’ll be making many more asteroid occultation observations in the lead-up to the Lucy mission’s arrival, and anyone with an eVscope can join in! Learn more about asteroid occultations on the Unistellar website, including predictions for occultations that will be visible near you.
