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 seven rocky planets of TRAPPIST-1 seem to...on January 22, 2021 at 4:02 pm
The red dwarf star TRAPPIST-1 is home to the largest group of roughly Earth-size planets ever found in a single stellar system. Located about 40 light-years away, these seven rocky siblings provide an example of the tremendous variety of planetary systems that likely fill the universe.
- Solar system formation in two stepson January 21, 2021 at 7:00 pm
An international team of researchers from the University of Oxford, LMU Munich, ETH Zurich, BGI Bayreuth, and the University of Zurich discovered that a two-step formation process of the early Solar System can explain the chronology and split in volatile and isotope content of the inner and outer Solar System.
- Indigenous lands: A haven for wildlifeon January 21, 2021 at 5:34 pm
Indigenous peoples' lands may harbor a significant proportion of threatened and endangered species globally, according to University of Queensland-led research.
- Rocks show Mars once felt like Icelandon January 21, 2021 at 2:21 pm
Once upon a time, seasons in Gale Crater probably felt something like those in Iceland. But nobody was there to bundle up more than 3 billion years ago.
- Climate-related species extinction possibly...on January 20, 2021 at 2:00 pm
Changes in climate that occur over short periods of time influence biodiversity. For a realistic assessment of these effects, it is necessary to also consider previous temperature trends going far back into Earth's history. Researchers from the University of Bayreuth and the University of Erlangen-Nuremberg show this in a paper for Nature Ecology and Evolution. According to the paper, future climate-related species extinction could be less severe than predictions based only on the current trend […]
