Venus is another interesting planet with a pink sky and has a high temperature of 400 degree celcius. On this planet there is also acid rain that falls all the time, but the raindroplets never do touch the ground for it evaporates the moment is falls due to the high temperature, and it rains again the moment it evaporates also as a result of the high temperature. It is the brightest planet in the solar system, and it can be seen with the naked eye in certain geographical locations shining like a star in the sky, the only difference is the planet will never twinkle like a star would.
