Detailed explanation-1: -Our Milky Way galaxy is just one of the billions of galaxies in the universe. Within it, there are at least 100 billion stars, and on average, each star has at least one planet orbiting it.
Detailed explanation-2: -Although the solar system has only one sun, most stars like Earth’s sun are binaries-two stars orbiting each other as a pair. Increasingly, astronomers are discovering planetary systems with twin suns (like Luke Skywalker’s fictional home planet Tatooine in “Star Wars").
Detailed explanation-3: -There are approximately 200 billion trillion stars in the universe. Or, to put it another way, 200 sextillion. That’s 200, 000, 000, 000, 000, 000, 000, 000! The number is so big, it’s hard to imagine.
Detailed explanation-4: -The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.
