On June 10, 2019, our planet Earth flies between the sun and the outer planet Jupiter. Our faster motion places Jupiter – largest world in our solar system, and an exceedingly bright planet in our sky – opposite the sun about once each year. In other words, Jupiter is now rising in the east as the sun is setting below the western horizon. Astronomers call this event an opposition of Jupiter.
Opposition marks the middle of the best time of year to see a planet. That’s because it’s when the planet is up all night and generally closest for the year
Jupiter is the 5th planet from the Sun and the largest planet in the Solar System. Tonight, with cloud cover permitting viewing, Jupiter will rise in the eastern sky after sunset, though it will take a few hours to get high enough to see it well. The best view should be around 11:30 pm in the southeast sky. Jupiter has 79 moons, 4 of them ( Io, Europa, Ganymede and Callisto) may be visible with binoculars.
