Detect Trojan Asteroid Rhesus and Discover More about our Solar System
On April 7, a Trojan asteroid known as 9142 Rhesus will occult (pass in front of) a star. This will be visible across a path sweeping over North America. Trojan asteroids are located in two groupings which orbit ahead and behind Jupiter. They were most likely captured 4 billion years ago during Jupiter’s migration towards the Sun, so they may contain clues on the history of our solar system.

New Opportunity: Detect a Brown Dwarf!
Unistellar citizen astronomers based all over the world can take part in a new challenge: detecting a brown dwarf! On April 6, 13, 20, and 28, a brown dwarf will transit (pass in front of) its star, from our view here on Earth. This brown dwarf was recently discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS) mission, and if successful, this would be the first brown dwarf detection by eVscopes!
But what is a brown dwarf? It’s larger than a planet, but smaller than a star — it is in a completely different category.
