Terrestrial planet, telluric planet, or rocky planet is a planet that is composed primarily of silicate rocks or metals. Within the Solar System, the terrestrial planets are the inner planets closest to the Sun, i.e. Mercury, Venus, Earth, and Mars. The terms “terrestrial planet” and “telluric planet” are derived from Latin words for Earth (Terra and Tellus), as these planets are, in terms of structure, “Earth-like”.
Terrestrial planets have a solid planetary surface, making them substantially different from the larger giant planets, which are composed mostly of some combination of hydrogen, helium, and water existing in various physical states. — Wikipedia

Three NASA missions return first-light data
on September 21, 2018 at 5:44 pm
NASA's continued quest to explore our solar system and beyond received a boost of new information this week with three key missions proving not only that they are up and running, but that their science potential is exceptional. On Sept. 17, 2018, TESS—the Transiting Exoplanet Survey Satellite—shared its first science observations. Later in the week, the latest two missions to join NASA's heliophysics fleet returned first light data: Parker Solar Probe, humanity's first mission to […]

A month before the planned launch of the joint ESA-JAXA BepiColombo mission to Mercury, two new studies shed light on when the innermost planet formed and the puzzle of its chemical composition. The findings will be presented by Bastien Brugger and Thomas Ronnet at the European Planetary Science Congress (EPSC) 2018 in Berlin. […]
