Planet Equilibrium Temperature Calculator

Estimate equilibrium temperature Tstar√(Rstar/(2d)) for zero albedo.

How to use the Planet Equilibrium Temperature Calculator

Estimate equilibrium temperature Tstar√(Rstar/(2d)) for zero albedo.

Step-by-step instructions

  1. Enter or select Star temperature (K).
  2. Enter or select Star radius (m).
  3. Enter or select Orbital distance (m).
  4. Tap Calculate.
  5. Review the result shown directly below the calculator.

What the inputs mean

Star temperature (K)
Enter the value requested by this field label.
Star radius (m)
Enter the value requested by this field label.
Orbital distance (m)
Enter the measurement shown, using consistent units.

Formula or calculation method

The calculator applies the standard mathematical relationship for the labeled inputs and returns the computed result automatically.

Example

Try entering realistic values for Star temperature (K) and Star radius (m), then tap Calculate to see how the result changes.

How to understand the result

Use the result as an estimate based on the values you entered. For planning decisions, double-check that the input units and assumptions match your real situation.

Tip: Keep all values in compatible units and use values from the same time period when the calculator compares two amounts.
