A difference between hot Jupiters and terrestrial USP planets is the proximity of planetary companions. Hot Jupiters are rarely found with other planets within a factor of 2–3 in orbital period or distance. In contrast, terrestrial USP planets almost always have longer-period planetary companions. [1]
In his 2019 book Identified Flying Objects and subsequent 2022 volume The Extratempestrial Model, Dr Masters explored more in depth various aspects of the time-traveler hypothesis, including fringe ancient astronauts theories and possible future development scenarios of human anatomy such as brain growth, craniofacial evolution, bipedalism ...
In 1952, science fiction writer James Blish coined the term gas giant [3] and it was used to refer to the large non-terrestrial planets of the Solar System.However, since the late 1940s [4] the compositions of Uranus and Neptune have been understood to be significantly different from those of Jupiter and Saturn.
The Rare Earth hypothesis argues that planets with complex life, like Earth, are exceptionally rare.. In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity, such as sexually reproducing, multicellular organisms on Earth, and subsequently human intelligence, required an improbable combination of astrophysical ...
Scientific modelling is an activity that produces models representing empirical objects, phenomena, and physical processes, to make a particular part or feature of the world easier to understand, define, quantify, visualize, or simulate.
Therefore, prograde spin with a small axial tilt, common for the Solar System's terrestrial planets except Venus, is not common in general for terrestrial planets built by giant impacts. The initial axial tilt of a planet determined by giant impacts can be substantially changed by stellar tides if the planet is close to its star and by ...
The Boston Museum of Science had placed bronze models of the planets in major public buildings, all on similar stands with interpretive labels. [1] For example, the model of Jupiter was located in the cavernous South Station waiting area. The properly-scaled, basket-ball-sized model is 1.3 miles (2.14 km) from the model Sun which is located at ...
Illustration of the inferred size of the super-Earth CoRoT-7b (center) in comparison with Earth and Neptune. A Super-Earth or super-terran or super-tellurian is a type of exoplanet with a mass higher than Earth, but substantially below those of the Solar System's ice giants, Uranus and Neptune, which are 14.5 and 17.1 times Earth's, respectively.
