Asteroid Program

Check our dedicated page to learn more about asteroid occultations which could be detected with an eVscope, take a look at when, where and how you could contribute to a better knowledge of asteroids.

Unistellar is also launching at the same time a beta Planetary Defense program, check the dedicated section to get an idea of how you could participate.

Are you willing to contribute to citizen science with your eVscope for one of these campaigns? Please send us an email at citizenscience@unistellaroptics.com

What’s new: SETILive with Ed Lu!!

Join the SETI Institute for a special #SETILive about Planetary Defense with American physicist and former NASA astronaut, Ed Lu. Ed will share his first-hand experience with a Unistellar eVscope and talk citizen science.

 

When and where ?

Will an occultation be observable nearby you ? Yes if you are nearby a red line, possibly if you are between the orange line.

How

  • What is an occultation ?

It is an astronomical event defined by the passage of an asteroid in front of a star. The latter is then completely or partially masked.

  • Why observe them?

To participate in scientific missions that study the asteroids around us and perhaps help discover the origins of life!

  • “What a Feeling”: A Testimonial from an Occultation’s Detector

Here is what Morand, one of Unistellar’s first citizen astronomers, wrote about his detection of asteroid 2000 UD52:

“When I received this occultation “mission”, I was a little confused. It seemed quite simple, the event was known, so no chance discovery by amateurs … But hey, I played the game. I had just received the telescope.

Excited but a little late as always, I followed the procedure and … I saw nothing … However, I sent the data. And, a few days later, I learned that the occultation was clearly visible on the data, that I was the only Unistellar to have observed it, and that the scientific value was real : the occultation was very brief, 0.3s (the predicted maximum was 0.8s), therefore particularly difficult considering the small size of the asteroid (~ 6.6 km) and the width of its centrality band.

Having observers near and into the centrality band will allow to better determine the position of the asteroid, and therefore to refine its orbit ! What a feeling !”
