Is Venus Earth’s sister?
Venus is very similar to Earth in size and mass – and so is sometimes referred to as Earth’s sister planet – but Venus has a quite different climate. Venus’ thick clouds and closeness to the Sun (only Mercury is closer) make it the hottest planet – much hotter than the Earth.
What is the biggest star in the sky right now?

Why do stars twinkle?
As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star’s appearance to wobble or twinkle.
