Objects Beyond Neptune Meagan Elvena Dakota Abalos Jacqueline Lujan Fernando Lopez While you watch.. • Take notes off the powerpoint • Watch the videos closely • There might be a prize for remembering any information we talk about during this powerpoint.. Which of the following separates outer planets from the inner planets? • YouTube Search Powered by iBoss • According to research, dwarf planets and the asteroid belt separate the planets All about the kuiper belt • A region of the solar system that starts just beyond the orbit of Neptune and that contains dwarf planets and other small bodies made mostly of ice • Looks like a doughnut-shaped ring just beyond the orbit of Neptune • Short period comets originate in the Kuiper Belt • There may be hundreds of thousands of icy bodies larger than 100 km (62 miles) and an estimated trillion or more comets within • Some dwarf planets within the Kuiper Belt have thin atmospheres that collapse when their orbit carries them farthest from the sun • Several dwarf planets in the Kuiper Belt have tiny moons • This region of space is not capable of supporting life What does it look like? Which of the following celestial bodies do scientists not consider a major planet? • YouTube Search Powered by iBoss • Pluto is not considered a major planet Exoplanets • Several hundred planet-like objects have been attributed to stars other than Earth’s sun because those objects circle stars other than Earth’s sun, they are called exoplanets • An exoplanet's size, orbit, and temperature can be deduced by observing the star it orbits • As of September 2014, there have been 1,743 confirmed discoveries of exoplanets • The first two exoplanets were discovered in 1992 • There are six different ways to search for exoplanets.. – – – – – – Radical Velocity Transit Photometry Micro lensing Astrometry Direct Imaging And searching for distant life in the moonlight WHAT DO THEY LOOK LIKE?
