All eyes on Mars! October 2020 is a big month for the Red Planet.
On Tuesday October 13th Mars will be at opposition — opposite the Sun’s position in the sky. On that date, the Earth is situated directly between Mars and the Sun. As a result, Mars rises as the Sun sets and sets as the Sun rises. Opposition — the most significant Martian date on stargazers’ calendars — is also when the planet is at its brightest and at its maximum apparent size in telescopes.
