'Opposition' will make Mars big and bright Tuesday night
Posted April 8, 2014
Every two years, Mars reaches a point on its orbit called opposition – when the planet lies directly opposite the sun and Earth.
With skies clearing late Tuesday, Triangle stargazers should be able to see Mars in most areas without a telescope.
Mars will rise Tuesday evening just a few minutes before sunset (7:43 p.m.), remain visible all night and set just a few minutes after sunrise (Wednesday, 6:50 a.m.).
Mars will appear bigger during the next opposition in May 2016 and even bigger on July 27, 2018. The brightness varies because the orbits vary and are not perfect circles.
Despite its visibility, Mars still remains 0.62 AU (57.74 million miles) from Earth, so stargazers won't be able to make out features of the red planet.
