All four inner planets in the Solar System are silicon-based. In the Federation standard system of planetary classification, a class K (or K type) planet was characterized as being adaptable for Humans by use of pressure domes and life support systems. Most of these reside in the Kuiper Belt with the exception of one which is Ceres in our asteroid belt. The following is a list of planet types by their mass, orbit, physical and chemical composition, or by another classification. Earth, third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. Silicate planets– the most commonly seen planets in the Solar system.Mostly formed of a silicon-created rocky mantle and iron core. Learn more about Pluto in this article. One of the best examples of this classification of volcanoes would be Kilauea which has been erupting since 1983. It is generally thought that the size of a terrestrial planet cannot be much larger than a couple of times the size of the Earth, and certainly not as large or as massive as Uranus, Neptune, Saturn, and Jupiter. The Earth-like or "terrestrial" planets - Mercury, Venus, Earth, and Mars - are small and rocky. inner planets: Mercury, Venus, Earth and Mars. A planet that does not orbit the Sun, but a different star, a stellar remnant, or a brown dwarf. Poisonous gases completely cover its surface, hiding what lies beneath and violent storms prevent any landings of probes onto or images taken of the giant planet. Located beyond Neptune in the Kuiper Belt (ring of bodies past Neptune), Pluto is smaller than our own moon and reaches temperatures of -387°F (-233°C). This is not a fact. Though it is further away from the sun then Mercury, Venus is the hottest planet in the solar system and is able to be seen by the naked eye from Earth. Planet Analytic Feeds enables you to spend less time building models and image processing pipelines, and more time on the analysis that drives better decision-making. The planet Gao was originally a 9.92 on the classification scale, but was upgraded to Class 10 13y11m AV. Pulsar planet: A planet that orbits a pulsar or a rapidly rotating neutron star. Earth has one natural satellite, Luna.Earth is most associated with the United Federation of Star Systems as it is the birthplace of Humanity and the administrative capital of the UFSS. They are listed in order of their distance from the sun. Also known as a planetary-mass object (PMO). Nonetheless, certain planet types have been applied to other planetary-mass objects; the Pluto–Charon system has been referred to as "double dwarf planets", for instance. Definition is part of classification, and some members of the IAU's Planet Definition Committee have complained that the definition as adopted in Prague is not optimal. It’s even more general than asking whether an organism is a plant or an animal. Phloem and Xylem. Has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and. The term was coined by Isaac Asimov. Title: Geophysical Classification of Planets, Dwarf Planets, and Moons. Over the course of development, the types of some planets have changed. (2006). Like Uranus, Neptune has high traces of methane in its atmosphere, which contributes to its blue color. New planet classification 2. 1 Classification of life on planet Earth Maybe this is an odd title, but we can’t exclude the possibility that a. there is life out in the universe (the field of the so called exobiology) b. that the beginning of life on our planet was of extraterrestrial origin. The IAU defines that a planet in the Solar System must orbit around the Sun, has enough mass to assume hydrostatic equilibrium, and has "cleared its neighborhood". Ceres at this current time is still labeled as an asteroid though it has many characteristics of a dwarf planet. E.g. The mineral compo- sition may vary also with particle size at a particular site. Three of the four inner planets (Venus, Earth and Mars) have atmospheres substantial enough to generate weather; all have impact craters and tectonic surface features, such as rift valleys and volcanoes. by position relative to Earth: inferior planets: Mercury and … The asteroid belt between Mars and Jupiter forms the boundary between the inner solar system and the outer solar system. These classifications are: terrestrial planets (Mercury, Venus, Earth, and Mars), gas giants (Jupiter and Saturn), ice giants (Uranus and Neptune), and dwarf planets (Pluto, Eris, Haumea, and Makemake). It's orbit path around the sun takes 285 Earth years and it is made up of rock with an icy coating over the surface. Rogue planet The physical features of landforms include Categories: Also in News Comparative Planetology. A theoretical planet with an icy surface and consists of a global cryosphere. Venus — this toxic planet, primarily consisting of carbon dioxide, is next in line from the sun and contains a pressure index that would crush anyone who landed on its surface. Earth – The only planet in our solar system with liquid water on the surface. Has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, Has not cleared the neighborhood around its orbit, and. Planet X — according to Caltech researchers, there is a strong possibility that there is another planet in the far reaches of our solar system Planet X. Nicknamed "Planet Nine", as it is theorized it is the 9th planet in our system, there is no direct evidence that the planet exists, but there are several mathematical models and computer simulations that point to its existence. The name derives from the fairy tale ", A class of extrasolar planets whose characteristics are similar to Jupiter, but that have high surface temperatures because they orbit very close—between approximately 0.015 and 0.5 AU (2.2. The level of methane gases in its atmosphere account for its bluish color, but the main elements in Uranus' atmosphere is helium and hydrogen. Has cleared the neighborhood around its orbit. Table of Contents show. Wow! Planet Earth is home to trillions of organisms (living things), including animals and plants. Earth (also known as Gaia, Sol Prime, and Sol III) is the third planet in the Sol System and the homeworld of Humanity.It is also the first natural known Me-Class world to Humanity. The planets of the modern solar system are grouped into several different and sometimes overlapping classifications, as illustrated in the following figure: The planets inside the orbit of the earth are called the Inferior Planets: Mercury and Venus. There are three broad types of planets by mass: Jupiter-mass planet (class J), Neptune-mass planet (class N), and Earth-mass planet (class E) with subclasses a (super-), b (mid-) and c (sub-) in order of decreasing mass. The terms used by the Starmap for planets are not mutually exclusive, but for some reason, every planet has only one type. into compositionally distinct regions (Figure 1; see The Earth as a Planet). The four inner or terrestrial planets have dense, rocky compositions, few or no moons, and no ring systems. What are Landforms? Previous planet classification systems, namely the Kardashev Scale published in 1964, considered the scale of a species/civilization's energy consumption and manipulation (planetary, solar, and galaxy level). There are four main categories of classifications when determining the type of celestial body an object is. Assuming "size" is defined by linear dimension (or by volume), mesoplanets should be approximately 1,000 to 5,000 km (620 to 3,110 mi) in diameter. The planets inside the asteroid belt are termed the Inner Planets (or the Terrestrial Planets): Mercury, Venus, Earth, and Mars.
