    Bond, P. () Pluto and Charon: ice worlds on the ragged edge of the solar system, second edition. by S.A. Stern and J. Mitton (Book review) The Observatory: a . Pluto, formal designation Pluto, is the second-most-massive known dwarf planet in the Solar System (after Eris), and the tenth-most-massive body observed directly orbiting the Sun. Originally classified as the ninth planet from the Sun (in ), Pluto was recategorized as a dwarf planet and plutoid owing to the discovery that it is only one of several large bodies within the .

    spaces between the water molecules, 4 with gas/ice ratios as high as 3 to (by number) at 30 K. As the temperature of condensation increases above 30 K the amount of gas that can be trapped drops quickly by 6 orders of magnitude at the temperature of K, and different species are preferentially trapped, resulting in fractionation. Tag: jovian moons. Posted on Novem Novem with low bond and geometric albedos. Ariel is the brightest while Umbriel is the darkest. Charon and Pluto always present the.

    Here we report on the reflected spectra and albedos of extrasolar planets and brown dwarfs. To present as general a set of results as possible, we calculate the geometric albedo spectrum of each model planet. The actual reflected spectrum for a planet around an arbitrary star can beFile Size: KB. Abstract We present spectra of the nuclear regions of 50 nearby (D = 1 - 92 Mpc, median = 20 Mpc) galaxies of morphological types E to Sm. The spectra, obtained with the Gemini Near-IR Spectrograph on the Gemini North telescope, cover a wavelength range of approximately μm at R˜

There is a distinct difference in the continuum slope between Jupiter and Saturn which may be attributed to a difference in the dust content or composition of the two by: Near-infrared reflectance spectra of Pluto and Charon obtained on 65 nights at NASA's Infrared Telescope Facility (IRTF) during were recently presented by.

We report results from monitoring Pluto's to {\mu}m reflectance spectrum with IRTF/SpeX on 65 nights over the dozen years from to The spectra show vibrational absorption features of simple molecules CH4, CO, and N2 condensed as ices on Pluto's surface.

We carried out near-infrared spectroscopic observations (–μm). Pluto/Charon - Double Dwarf Planet. Above is a Hubble Space Telescope image of planet Pluto.

Below the HST image is a great photo of Pluto taken by the New Horizons satellite. Below is what Pluto might be feeling emotionally after being summarily demoted from the status of planet to that of lowly dwarf planet following the August, meeting of the International Astronomy Union.

The Pluto-Charon system is found to be compositionally diverse, a result unanticipated before the mutual events.

Water frost was identified and is ubiquitous on Charon's surface, while Pluto has a methane veneer. The spectral activity of Pluto's methane is seen to vary with rotational phase.
