The two planets will be just 35.8 million miles (57.6 million kilometers) apart next Tuesday. And on Friday, Mars will be in opposition. That means Mars and the sun will be on exact opposite sides of Earth. That same day, parts of the world will see a total lunar eclipse.

Mars is already brighter than usual and will shine even more— and appear bigger—as Tuesday nears. Astronomers expect good viewing through early August.
