A new gas giant world discovered by citizen scientists using data from NASA's exoplanet-hunting spacecraft TESS is cool, literally and figuratively.
The extrasolar planet, or "exoplanet," designated TOI-4465 b is located around 400 light-years from Earth. It has a mass of around six times that of Jupiter, and it's around 1.25 times as wide as the solar system's largest planet. What is really exciting about TOI-4465 b, however, is the fact that it circles its star at a distance of around 0.4 times the distance between Earth and the sun in a flattened or "elliptical" orbit. One year for this planet takes around 102 Earth days to complete. Its distance from its star gives it an estimated temperature of between 200 and 400 degrees Fahrenheit (93 to 204 degrees Celsius).
