    Interesting that it is called a cold world with an estimated surface temperature of just 190°C! The Earth must be super cool.

      I genuinely had no idea that most we've detected were above 1,000°C. That's crazy.

      Moreover, with an atmosphere temperature of only 190 Celsius degrees, HD88986b provides a rare opportunity for studying the composition of the so-called "cold" atmospheres, as most of the detected atmospheres for exoplanets are above 1,000° Celsius.

        Exoplanets are easier to discover the shorter their orbit periods are, and the orbit period is shorter the closer to their star they orbit, so most exoplanets discovered so far are very close to...

          Ah, so there is an available data bias at play in those temperatures making up "most". Makes sense. Thanks for the info!
