Dr. Chad Trujillo is the American astronomer who, along with Mike Brown and David Rabinowitz, discovered the dwarf planet Eris in 2005, a discovery that prompted the IAU to define “planet,” leading to Pluto’s reclassification. Eris, a massive Trans-Neptunian Object (TNO) with its own moon, Dysnomia, highlighted the need for new planetary criteria, ultimately establishing dwarf planets as a distinct category.

Now 9, Zoey still wants to be an astronaut and together, Jeff and Zoey have gone beyond their children’s books to create an entire Space & STEM brand for kids which includes books, STEM to Bloom magazine, running an observatory and STEM-themed virtual and in-person events, like this one. One of the highlights of our brand is the issue of STEM to Bloom we created in partnership with Lowell Observatory all about Pluto!
