Effect of Atmosphere on a Planet’s Dayside Temperature

Effect of Atmosphere on a Planet’s Dayside Temperature
Researchers can determine whether or not a tidally locked rocky planet has an atmosphere by comparing its measured temperature to computer models. The dayside temperature of TRAPPIST-1 b, for example, is very close to the model that assumes the planet has no atmosphere.

About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    23h 06m 30s
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    -05d 02m 30s
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Aquarius
  • 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.
    40 light-years
