Class M Planet
In the '' Star Trek'' universe, a Class M planet is one habitable by humans and similar life forms. Earth, Vulcan, Romulus, and Qo'noS are examples of Class M planets. The planet needs an atmosphere of oxygen and nitrogen, should be close to a stable star, have fertile soil, a tolerable gravity, a climate that is generally pleasant for humans. Most planets shown in the franchise are Class M planets; occasionally another alphabetically named class of planet is shown, each hostile to humanoid life in one or more ways. As a story device, this allowed for easy filming without restriction by environmental suits, but ''Science'' correspondent Gretchen Vogel called it a "failure of imagination" when thinking about the limits of the zone capable of supporting life. The origin within the fictional universe is implied to be the Vulcan word ''Minshara''. See also * Earth in science fiction An overwhelming majority of fiction is set on or features the Earth. This also holds true of science ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Class M Star
In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines. Each line indicates a particular chemical element or molecule, with the line strength indicating the abundance of that element. The strengths of the different spectral lines vary mainly due to the temperature of the photosphere, although in some cases there are true abundance differences. The ''spectral class'' of a star is a short code primarily summarizing the ionization state, giving an objective measure of the photosphere's temperature. Most stars are currently classified under the Morgan–Keenan (MK) system using the letters ''O'', ''B'', ''A'', ''F'', ''G'', ''K'', and ''M'', a sequence from the hottest (''O'' type) to the coolest (''M'' type). Each letter class is then subdivide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driver's License
A driver's license is a legal authorization, or the official document confirming such an authorization, for a specific individual to operate one or more types of motorized vehicles—such as motorcycles, cars, trucks, or buses—on a public road. Such licenses are often plastic and the size of a credit card. In most international agreements the wording "driving permit" is used, for instance in the Vienna Convention on Road Traffic. In this article's country specific sections, the local spelling variant is used. Most American jurisdictions issue a permit with "driver license" printed on it but some use "driver's license", which is conversational American English. Canadian English uses both "driver's licence" as well as "driver licence" ( Atlantic Canada). The Australian and New Zealand English equivalent is "driver licence". In British English and in many former British colonies it is "driving licence". The laws relating to the licensing of drivers vary between jurisdic ...
