Mars will be part of a cosmic alignment today. Pretty exciting stuff. I think this would make an excellent science lesson for students.
Mars will be exactly opposite the sun in the sky in a rare cosmic alignment set to take place Tuesday (April 8).
Called an opposition, this happens with Mars from Earth’s perspective every 778 days, or 2 years, 1 month and 18 days. Think of Earth and Mars as two cars racing on circular tracks. Because Earth is closer to the sun, it travels faster, completing a circuit in 365 days. Mars is farther from the sun and takes longer, 687 days. By the time Mars has completed one circuit, Earth has a lot of catching up to do to get to a point between the Red Planet and the sun. Click here to learn more.
