About The Object
Object Name Pluto
Object Description Dwarf Planet
Distance Pluto is on an eccentric orbit that varies between 29.6 AU and 49.3 AU from the Sun. The average distance during the time of these observations was 30.6 AU (Jan. 2003). In 2010, Pluto is 31.8 AU from the Sun and moving away. It will reach its furthest distance from the Sun in 2130.
Dimensions Pluto has a diameter of roughly 1,440 miles (2,320 km) at the equator.
About The Data
Data Description The image was created from Hubble data from proposals : A. Stern (Southwest Research Institute), L. Trafton (University of Texas, Austin), and M. Buie (Southwest Research Institute); and : M. Buie (Southwest Research Institute), W. Grundy (Lowell Observatory), and E. Young, L. Young, and A. Stern (Southwest Research Institute). The science team comprises: M. Buie (Southwest Research Institute), W. Grundy (Lowell Observatory), and E. Young, L. Young, and A. Stern (Southwest Research Institute).
Instrument HST>ACS/HRC
Exposure Dates June 2002 - June 2003
Filters F435W (B) and F555W (V)
About The Image
Color Info The image is a composite of separate exposures made by the ACS/HRC instrument on the Hubble Space Telescope. Two filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F435W (B) Green: F555W (V)
About The Object
Object Name A name or catalog number that astronomers use to identify an astronomical object.
Object Description The type of astronomical object.
R.A. Position Right ascension – analogous to longitude – is one component of an object's position.
Dec. Position Declination – analogous to latitude – is one component of an object's position.
Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
Distance The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
Dimensions The physical size of the object or the apparent angle it subtends on the sky.
