1 14b. Pluto, Kuiper Belt & Oort Cloud Pluto Pluto s moons The Kuiper Belt Resonant Kuiper Belt objects Classical Kuiper Belt objects Pluto Data: Numbers Diameter: 2,290.km Earth Mass: kg Earth Density: 2.0. water Earth Orbit: km AU Day: 6 d.09 h 17 m 51 s Earth Year: years Earth The Oort Cloud Pluto Data: Special Features Pluto is the farthest planet from the Sun Pluto is the smallest planet Pluto has a very thin atmosphere Pluto is much smaller than the Moon Pluto has only ~0.18. the mass of the Moon Pluto has only ~0.66. diameter of the Moon Pluto s interior likely consists of two layers An icy mantle (~25% of Pluto s mass) A rocky core (~75% of Pluto s mass) Pluto is extremely difficult to observe from Earth Pluto is extremely small & far from the Sun Pluto s moon Charon has ~0.08. Pluto s mass Pluto Data (Table 14-5) Pluto s Amazing Discovery The reason for a search Apparent discrepancies in Neptune s predicted orbit Actually no unaccounted perturbations of Neptune The actual search Percival Lowell Urged construction of a wide-field astronomical camera Camera was completed in 1929 Clyde Tombaugh worked at Lowell Observatory Discovered Planet X on 18 February 1930 Announced discovery on 13 March 1930 Some obvious problems Much more dim & small than expected More highly elliptical orbit than any other planet More steeply inclined orbit than any other planet Pluto & Charon Are Unique Objects Planetary patterns Terrestrial planets H 2 & He poor planets with solid surfaces Satellites much smaller than parent planets Jovian planets H 2 & He rich planets with no solid surfaces Satellites much smaller than parent planets Pluto s patterns Composition Mixture of ices & rock with a solid surface Satellite Closest in mass & diameter of all Solar System pairs
2 The Discovery of Charon U.S. Naval Observatory James W. Christy 1978 Examined existing photographs of Pluto Noted a bulge on one side Examination of other photos confirmed a moon Fundamental characteristics Orbital period of ~ 6.4 days < 5 % the Earth-Moon distance Mutual synchronous axial rotation One side of Charon always faces Pluto One side of Pluto always faces Charon Determining Surface Characteristics An extremely rare alignment Charon s line of nodes points directly toward Earth Throughout the years 1985 to 1990 Mutual eclipses of Pluto & Charon Determined most accurate sizes of Pluto & Charon Determined generalized brightness patterns of Pluto & Charon The Hubble Space Telescope Also helpful in determining surface brightness Kuiper Belt Objects (KBO s) Hypothesized Gerard Kuiper 1951 Proposed a source region for some comets Discovered David Jewitt & Jane Luu 1992 Found 1992 QB 1 ~ 42 AU from the Sun Spectrally very similar to Pluto & Charon More than 1,000 KBO s have been discovered Quaoar discovered June 2002 Quaoar measured September 2002 ~ 1,300 km in diameter & in a nearly circular orbit Implications Pluto & Charon may be the closest & largest KBO s Should we still consider Pluto a planet??? Computer-Derived Views of Pluto Kuiper Belt Objects (KBO s) Hypothesized Gerard Kuiper 1951 Proposed as a source region for short-period comets Discovered David Jewitt & Jane Luu 1992 Found 1992 QB 1 ~ 42 AU from the Sun Spectrally very similar to Pluto & Charon 1,352 known KBO s as of early 2008 Quaoar discovered 4 June 2002 Quaoar measured September 2002 Quaoar announced 7 October 2002 ~ 1,300 km in diameter & in a nearly circular orbit Implications Pluto & Charon may be the closest large KBOs I.A.U. no longer considers Pluto a [major] planet!!!
