About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.18h 5m 16.36s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.-28° 53' 42.0"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Sagittarius
- DistanceDistanceThe 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.19,000 light-years (5.8 kiloparsecs)

This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope using several different filters. Three filters sample broad wavelength ranges, one isolates the light of hydrogen. 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) Red: F814W (I)

Artist's View of Planet Around a Red Dwarf
This is an artist's concept of a gas giant planet orbiting a red dwarf K star (system name OGLE-2003-BLG-235L/MOA-2003-BLG-53L). The planet has not been directly imaged, but its presence was detected in 2003 microlensing observations of a field star in our galaxy. Gravitational...
