On Wednesday (March 1) and Thursday (March 2), two bright planets will appear as if they were about to collide in the night sky.
Jupiter, the largest planet in the solar system, and Venus, one of the brightest objects in Earth's sky, will come within about half a degree of each other — or roughly one full moon's width apart. For weeks, the two bodies have been inching closer together, building toward a phenomenon called a conjunction, which occurs whenever two objects in the sky — such as moons, planets or stars — appear exceptionally close together.
This phenomenon is, of course, a trick of perspective. The two bright planets are in fact millions of miles apart; only from our point of view on Earth do they appear to butt against each other. Thanks to the orbital patterns of Earth, Jupiter and Venus, conjunctions like this occur once every year or so.
You won't need a telescope or binoculars to see the two bright planets. Simply look to the west after sunset, and the two canoodling objects should be apparent to the naked eye. They will look like exceptionally bright stars; Jupiter will shine twice as bright as Sirius, the brightest star in the sky, while Venus will blaze six times brighter than Jupiter, according to Live Science's sister site Space.com (opens in new tab).
However, skywatchers who do view the planets through a pair of binoculars may have the bonus of seeing three of Jupiter's largest moons: Io, Ganymede and Callisto.

The two planets will be separated a bit too widely to appear in the same field of view of a telescope, according to In-The-Sky.org (opens in new tab).
If you can't catch this spectacle in the sky, you can watch a livestream of the conjunction, as seen from Rome, courtesy of the Virtual Telescope Project (opens in new tab). The stream begins at 1:30 p.m. EST (1830 GMT) on March 1.
