2 Topics Asteriod Belt Pictures History of Discovery Kuiper Belt Theories Comets Meteoroids Meteors Merteorites The Difference Between the three m/asy/objects/images/hu bble-galaxy- silhouettejpg.jpg

3 The Asteroid Belt The Main Belt Located roughly between Mars and Jupiter Comprised of asteroids and minor planets – Half the mass in 4 bodies Ceres (smallest Dwarf Planet) 4 Vesta, 2 Pallas, 10 Hygiea – Diameter more than 400 m Smallest bodies range down to dust particles Asteroids can be classified by spectra – carbonaceous (C-type), Silicate (S-type), Metal- rich (M-type)

6 History of Observations In 1800 astronomer Franz Xaver von Zach assembled the Celestial Police Searching for the missing planet between mars and Jupiter Based off Predictions by Johann Daniel Titius vonWittenburg In 1801 Giuseppe Piazzi discovered the planet Ceres William Herschel categorized Ceres and the other dwarf planets as asteroids, star like Giuseppe Piazzi org/wikipedia/commons/ 9/92/Giuseppe_Piazzi.jpg

7 Kuiper Belt Lays outside Neptunes orbit Similar to Asteroid belt except much larger Comprised of frozen volatiles – Methane, ammonia, water (ice) – Pluto, Haumea, Makemake Discovered in 1992 after the discovery of Pluto (might not be alone)

9 History and Theories Fredrick Leonard: First Astronomer to suggest outer Neptunian bodies Kenneth Edgeworth: hypothesized that the region beyond Neptune was too widely spaced for Planets Gerard Kuiper: suggested a disk outside Neptune Gerard Kuiper pedia/commons /0/0b/GerardKui per.jpg

10 Comets Small Solar System bodies that orbit the sun – Orbital periods take up to hundreds of thousands of years – Short period comets originate in the Kuiper Belt – Thrown out of the belt by gravitational pulls Coma (fuzzy atmosphere) and a tail Ice, dust, rocky particles Range from a few km- 10 km across 3,648 known comets (increasing)

12 Meteoroids/Meteors/Meteorites Meteoroids- sand (micrometeoroids) to boulder size, part of meteor showers – Orbit the sun at various velocities – Collide with Earth if in retrograde motion at speeds ~70km/s Meteoroids that enter earths atmosphere are meteors Meteors that reach Earths surface are meteorites
