" The Secrets of Planet Rotation and Tilt " //© astro.voyagers

Planet’s “rotation” refers to its spinning motion about its own axis. One full rotation around equals 1 full day on that particular planet. Each planet has its own rotation time speed and the length of a day on each planet is noted on screen. Jupiter has the quickest day which is ~ 9 hours and 55 minutes long. Venus has the longest day which is an astonishing 243 EARTH DAYS and 26 minutes long!! That’s DAYS and not HOURS!! In other words Venus rotates VERY slowly. KEY TO REMEMBER: 🔑 Jupiter spins very quickly. 🔑 Venus spins very slowly. TIMES TO REMEMBER: Approximate day length of each planet (from shortest to longest): Jupiter: 9 hours, 55 minutes. Saturn: 10 hours, 33 minutes. Neptune: 16 hours. Uranus: 17 hours, 14 minutes. Earth: 23 hours, 56 minutes. Mars: 24 hours, 36 minutes. Mercury: 58 EARTH days, 16 hours. Venus: 243 EARTH days, 26 minutes. Mercury has a scorching daytime temperature and a freezing nighttime chill due to its lack of atmosphere. Venus experiences extreme greenhouse effect, making it the hottest planet despite being the second from the Sun. Earth’s axial tilt gives us seasons, shaping the world’s climate and ecosystems. Mars’ tilt creates dramatic climate variations, including polar ice caps and dusty storms. Jupiter’s rapid rotation creates its iconic bands of clouds and the Great Red Spot, a giant storm. Saturn’s tilt gives us stunning views of its magnificent ring system. Uranus’ peculiar tilt may have been caused by a massive collision in its distant past.
