Gale (crater) about above the floor of Gale—three times higher than the Grand Canyon is deep. At 10:32 p.m. PDT on Aug. 5, 2012 (1:32 a.m. EDT on Aug. 6, 2012), the Mars Science Laboratory rover "Curiosity" landed on Mars at , at the foot of the layered mountain inside Gale crater. "Curiosity" landed within a landing ellipse approximately by . The landing ellipse is about below Martian "sea level" (defined as the average elevation around the equator). The expected near-surface atmospheric temperatures at the landing site during "Curiosity"s primary mission (1 Martian year or 687 Earth days) are from to .
Gliese 687 X-rays. Gliese 687 Gliese 687, or GJ 687 "(Gliese–Jahreiß 687)" is a red dwarf in the constellation Draco. This is one of the closest stars to the Sun and lies at an approximate distance of less than 15 light years. Even though it is close by, it has a magnitude of about 9, so it can only be seen through a moderately sized telescope. Gliese 687 has a high proper motion, advancing 1.304 arcseconds per year across the sky. It has a net relative velocity of about 39 km/s. It is known to have a Neptune-mass planet. Gliese 687 has
