The largest planet in the solar system, Jupiter, will be perfectly in-line with the Earth and the Sun on Monday night.
This yearly occurrence, which is called opposition, makes the planet glow almost as bright as the moon.
The Franklin Institute Chief Astronomer, Derrick Pitts, said the planet will appear in the southeastern night sky and will be "the largest, brightest object you can see other than the moon."

Should you use binoculars, Pitts said that "you'll even be able to see anywhere between one and four of its largest moons."
Unfortunately, the greater Philadelphia area is forecast to be engulfed with rain and clouds until Tuesday morning, but you can catch a glimpse of Jupiter all summer long.
"You'll be able to see it almost as close tomorrow night and although it will be drifting away from us through the rest of the summer, it still will appear very large and very bright and easily recognizable by anyone," Pitts said.
