Mars and Jupiter get chummy in the night sky. The planets won't get this close again until 2033

Mars and Jupiter are cozying up in the night sky for their closest rendezvous this decade. They'll be so close Wednesday, at least from our perspective, that just a sliver of moon could fit between them. In reality, our solar system's biggest planet and its reddish neighbor will be more than 350 million miles apart. Their orbits haven't brought them this close together, one behind the other, since 2018. And it won't happen again until 2033. Known as planetary conjunctions, these cosmic pairings happen only every three years.
