If you missed seeing Mars in the night sky last week during its close approach, you have another chance Tuesday night.
The red planet will be visible to the human eye once again because of a phenomenon called opposition, which occurs when Mars and the sun are located on opposite sides of the earth, according to NASA.
This means ― from the perspective of people on Earth ― that the sun is setting in the west as Mars rises in the east.
The phenomenon, which occurs every two years, makes the planet appear bigger and brighter than usual.
Mars’ opposition is happening exactly a week after its closest approach, which occurs when Mars and Earth are near each other in their orbits.
