Is the moon a moon or planet?
Rather than being a planet or a star, the moon is a natural satellite that orbits the Earth. The moon formed around 4.5 billion years ago due to a collision between the Earth and another planet. The debris from this collision entered into Earth’s orbit and eventually coalesced to form the moon.
What is the most beautiful star?
Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth’s night sky. The name means “glowing” in Greek — a fitting description, as only a few planets, the full moon and the International Space Station outshine this star. Because Sirius is so bright, it was well-known to the ancients.
