HD 12235 b
Neptune-like planet, scorching orbiting HD 12235, 104 light-years from the Sun
Nobody has seen this planet up close. The model is computed from the values below: it shows what a planet of this size and temperature could look like. Drag it to look at every side, zoom with the buttons, with two fingers or with Ctrl and the mouse wheel.
Planet
- Radius
- 3.23 × Earthcalculated
- Mass
- 10.5 × Earthminimum mass
- Density
- 1.71 g/cm³calculated
- Equilibrium temperature
- 1,667 K (1,394 °C)calculated
- Starlight received
- 1,288 × Earthcalculated
“Calculated” marks values that were derived from other measurements instead of being measured. “Minimum mass” means that only a lower limit is known, the true mass may be higher. The equilibrium temperature ignores any atmosphere, so the surface can be much warmer.
Orbit
- Orbital period
- 4.36 days
- Distance from the star
- 0.054 AU
- Eccentricity
- 0.376
1 AU is the distance between Earth and the Sun. An eccentricity of 0 is a perfect circle.
