Astronomy
Exoplanet Habitability Calculator
Estimate an exoplanet's effective surface temperature and habitability based on its host star and orbital parameters. Use this when evaluating whether a discovered or hypothetical planet could support liquid water.

Astronomy
Meteor Shower Activity Calculator
Estimate how many meteors per hour you will actually see during a meteor shower, accounting for radiant altitude, sky darkness, and moonlight. Use it on the night of a shower to set realistic expectations.
