List of coolest exoplanets

Short description: none

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.

This is a list of the coolest exoplanets known, specifically those with temperatures lower than −75 °C (198 K). Planets from the Solar System were also included for comparison for purposes.

Discovered in 2006, OGLE-2005-BLG-390Lb is the coldest known exoplanet, and was nicknamed "Hoth" by NASA in reference to the planet from the Star Wars franchise.[1] Image

1. ↑ Teff: Measured effective temperature. Teq: The temperature of the planet has not been measured, so it is listed with the calculated equilibrium temperature.
2. ↑ The melting points of elemental Nitrogen and Oxygen at 1 bar pressure are -210 °C and -218 °C, respectively.[2][3]
3. ↑ This was obtained using the CalcTool luminosity converter. Using the apparent magnitude of HIP 11915 and its distance from Earth (using the uncertainty parameter of ±10 light years), this yields a range of 1.03–1.27 L☉. When used in the default 190 light-year distance (with margin of error) is 1.07+0.11
−0.09 L☉. When run into simulations using the orbital distance of HIP 11915 and its planet, yields a result of 118 K.
4. ↑ This is the surface temperature if GJ 1002 c has no atmosphere.
5. ↑ This is the surface temperature if Kepler-186f has no atmosphere.
6. ↑ This is the surface temperature if TRAPPIST-1g has no atmosphere.
7. ↑ M⊕: Earth mass MJ: Jupiter mass

1. ↑ The age is the same as the globular cluster where PSR B1620-26b is located (Messier 4), as all the stars in the cluster formed at the same time, and the planets form together with their host stars.
