android A fictitious robot with artificial intelligence. The term was created for use in the Star Wars universe, and is short for android.

exotic An adjective for describing something that is highly unusual, strange, or strange (such as exotic plants).

geology The study of the structure and physical substance of the Earth, its history and the processes that act on it. The people who work in this field are known as geologists. Planetary geology is the science of studying the same things about other planets.

habitat The area or natural environment in which an animal or plant normally lives, such as a desert, a coral reef or a freshwater lake. A habitat can be home to thousands of different species.

hue A color or tone of some color.

Kuiper Belt An area of ​​the solar system beyond the orbit of Neptune. It is a vast area containing remnants of the formation of the solar system that continue to orbit the sun. Many objects in the Kuiper belt are made of ice, rock, frozen methane and ammonia. The best known of the larger objects of the Kuiper Belt is the dwarf planet Pluto. The belt extends from the sun at a distance of 30 to 55 astronomical units. (An astronomical unit is equal to that of Earth from the sun.)

Wolf A rounded and slightly flat projection. Many leaves, for example, lobed edges.

methane A hydrocarbon of the chemical formula CH4 (meaning that there are four hydrogen atoms attached to a carbon atom). It is a natural constituent of what is known as natural gas. It is also emitted by the decomposition of plant material in wetlands and is expelled by cows and other ruminant animals. From a climate point of view, methane is 20 times more potent than carbon dioxide in capturing heat in the Earth's atmosphere, making it a very important greenhouse gas.

NASA Abbreviation for the National Aeronautics and Space Administration. Established in 1958, this US agency has become a leader in space research and in stimulating the public interest in space exploration. It was through NASA that the United States sent people to orbit and finally to the moon. He also sent a research vessel to study planets and other celestial objects in our solar system.

native Associated with a certain location; native plants and animals have been found at a specific location since recorded history began.

nitrogen A colorless, odorless and non-reactive gaseous element that forms about 78% of Earth's atmosphere. Its scientific symbol is N. Nitrogen is released in the form of nitrogen oxides, as fossil fuels burn.

physics The scientific study of the nature and properties of matter and energy.

planet A celestial object that orbits a star is large enough that gravity has crushed it in a rounded ball and has removed other objects from the path in its orbital neighborhood. To accomplish the third feat, the object must be large enough to have drawn neighboring objects to the planet itself or to throw them around the planet and into outer space.

Pluto A dwarf planet located in the Kuiper belt, just after Neptune. Pluto is the tenth largest object orbiting the sun.

primordial An adjective that refers to something that goes back to the beginning of time or to the oldest existence of something.

radiation (in physics) One of the three main ways in which energy is transferred. (The other two are conduction and convection.) In radiation, electromagnetic waves carry energy from one place to another. Unlike conduction and convection, which need material to help transfer energy, radiation can transfer energy through the empty space.

solar system The eight major planets and their moons orbit around our sun, along with smaller bodies in the form of dwarf planets, asteroids, meteoroids and comets.

Star The basic building block from which the galaxies are made. Stars develop when gravity compacts clouds of gas. When they become dense enough to sustain nuclear fusion reactions, stars emit light and sometimes other forms of electromagnetic radiation. The sun is our closest star.

Sun The star at the center of the Earth's solar system. It is a medium-sized star about 26,000 light-years away from the center of the Milky Way. Also a term for any star resembling the sun.
