Today’s source of Inspiration is exploration and knowledge gained through exploration. Our universe is filled with places to explore and much to learn. Jupiter is the fifth planet from our Sun.
Jupiter is a giant gas planet in our Solar System. Jupiter has been known since ancient times and is one of the brightest objects in the night sky, behind the Moon and Venus. It is made up of mostly hydrogen and some helium. It is thought to have a rocky core, but does not have a solid surface. The atmosphere has distinct layers. There are storms at their boundaries. A prominent feature is the Great Red Spot in Jupiter’s southern hemisphere. The Great Red Spot is a massive storm that was first observed there in the 17th century. Jupiter has a faint planetary ring and a strong magnetosphere.
Jupiter is known to have 67 natural satellites. The four Galilean moons were discovered by Galileo Galilei in 1610. Well over half of Jupiter’s moons are less than 10 kilometers in diameter. Jupiter’s moons are currently grouped into six categories. Their size, shape, and orientation are used for their grouping.
Jupiter is hit by comets and asteroids more than other planets. Gravity from Jupiter affects their trajectory and some believe it attracts them and others believe it repels them. Either way, the result is about 200 times more asteroid and comet hits on Jupiter than on Earth.
A number of automated spacecraft have visited Jupiter. The Pioneer 10 space probe was the first to send back revealing information about Jupiter. Several flyby missions have occurred. NASA’s Juno mission is currently in polar orbit studying the planet. Future missions are planned.
Jupiter is inspirational and learning about it is inspirational. Be inspired! Have a bright day!
