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

    The planetary system around star HR8799 is remarkably similar to our solar system. It has four gas giants in between two asteroid belts. A research team led by RuG and SRON used this similarity to model the delivery of materials by asteroids, comets and other minor bodies within the system. Their simulation shows that the four gas planets receive material delivered by minor bodies, just as in our solar system.

    A ZSL study published in Nature Communications today maps the evolutionary history of the world's terrestrial vertebrates—amphibians, birds, mammals and reptiles—for the first time, exploring how areas with large concentrations of evolutionarily distinct and threatened species are being impacted by our ever-increasing 'human footprint'.

  • Astronomers recategorize asteroid-like comet
    on May 27, 2020 at 12:07 pm

    Recently discovered object 2019 LD2, originally believed to be the first cometary "Jupiter Trojan" asteroid by astronomers at the University of Hawaiʻi at Mānoa Institute for Astronomy turns out to be an interloper comet masquerading as a member of the Trojan population. The distinction was first suggested by amateur astronomers Sam Deen and Tony Dunn on the Minor Planet Mailing List on May 21 and confirmed by UH's Asteroid Terrestrial-impact Last Alert System (ATLAS) colleagues Alan […]

    Five years after NASA's MAVEN spacecraft entered into orbit around Mars, data from the mission has led to the creation of a map of electric current systems in the Martian atmosphere.

    We often think of asteroids and comets as distinct types of small bodies, but astronomers have discovered an increasing number of "crossovers." These objects initially appear to be asteroids, and later develop activity, such as tails, that are typical of comets.
