By: Dr. Marcelo Emilio
When: Friday 4/20 at 9:30 PM SLT (6:30 PM HST)
Dr. Marcelo Emilio will be talking about “The New Solar System”
"In 2006, the International Astronomical Union modified the definition of 'planet' and created a new category, 'dwarf planet,' that includes some of the larger asteroids and trans-Neptunian objects, the icy bodies orbiting the Sun beyond Neptune. In the last decade, both spacecraft sent to explore the solar system and ground-based observations have made exciting discoveries, including new dwarf planets and several moons. In this talk, Dr. Marcelo Emilio (Universidade Estadual de Ponta Grossa, Brazil) will cover several characteristics of planets, dwarf planets, moons, comets, and asteroids, and he will describe a technique called "stellar occultation" that is used to get information about trans-Neptunian objects."
