Exoplanets and the search for life
Main lesson
An exoplanet’s orbit from its period
Use this for “A planet circles a star of 0.5 solar masses every 1,461 days. How far is it from its star?”
The habitable zone and a planet’s temperature
Use this for “A star gives off 0.25 times the Sun’s light. Where is its habitable zone, and is a planet at 0.5 AU in it?”
How exoplanets are found
Use this for “Which planets are easiest to find by transits, by the Doppler wobble or by imaging?”
Searching for life
Use this for “Which findings would show a world could hold life, and which would show life itself?”
