The innermost of the three known worlds of upsilon Andromedae hugs it star in an orbit so tight that the planet glows red from the incident heat and clouds of ice particles cannot form. Tidally locked long ago, one side of the planet always faces its sun. The temperature at the spot closest to the sun is so high that gases are ignited and rush to the cool side of the planet. No calm cloud bands here, this is a seething atmosphere constantly turning itself inside out.
