About The Object
Object Name S/2004 N 1, Neptune
Object Description Planet and Recently Discovered Neptunian Moon
Distance The semi-major axis of Neptune's orbit about the Sun is 30.06 astronomical units (roughly 2.8 billion miles or 4.5 billion kilometers).
About The Data
Data Description This image was created from HST data from proposal : M. Showalter (SETI Institute), I. de Pater (University of California, Berkeley), and J. Lissauer (NASA Ames Research Center).
Instrument HST>WFC3/UVIS
Exposure Dates August 19, 2009
Filters F475W (g), F606W (V), and F775W (i)
About The Image
Color Info This image is a composite of many separate exposures made by the WFC3/UVIS instrument on the Hubble Space Telescope using three different filters. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F475W (g) Grayscale: F606W (V) Red/orange: F775W (i)

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.
