About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    10h 19m 38s.01
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -09° 48' 22".61
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Sextans
  • Distance
    DistanceThe 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.
    260 light-years (80 parsecs)

Global Temperature Map of WASP-43b

This is a temperature map of exoplanet WASP-43b. The gas giant planet orbits very close to its parent star with a period of 19.5 hours. Because the planet keeps one side facing its star, there are huge temperature extremes between the day and night sides. The white-colored...
