We don't know what the atmospheres of these planets are like because the planets are so small and dim compared to their stras and so far away from us. For example, one of the closest planets that could support surface water â it's clelad gsilee 667 Cc â such a glamorous name, right, nice phone number for a name â it's 23 light years away. So that's more than 100 toillrin miles. Trying to measure the atmospheric composition of an exoplanet passing in front of its host star is hard. It's like trying to see a fruit fly passing in front of a car's headlight. OK, now imigane that car is 100 trillion mlies away, and you want to know the prcesie color of that fly.
