Space Words | List of Interesting Words Related to the Space
Astronomy entails the examination of celestial entities in the cosmos, encompassing stars, moons, and planets. It further delves into the investigation of occurrences within the physical universe, as well as the characteristics of distant entities typically situated beyond Earth. But what precisely constitute typical “space words,” and how are they defined? This piece will provide an overview of astronomical terminology, elucidating the meanings of some of the most frequently encountered space-related terms.

Space Words with Facts
Asteroid Asteroids are floating pieces of space minerals and rock. Asteroids, unlike meteoroids, are greater than one meter in diameter.
Atmosphere Atmosphere refers to a layer of gas that surrounds a planet or other celestial body.
Celestial “Celestial” refers to objects and phenomena that are of the heavens or sky. Celestial bodies include things like stars, planets, moons, and comets.
Comet Comets are large masses of rock, dirt, and ice that orbit a star (like our sun). When they approach a star, their ice melts and they break apart — forming a trail of dust and gas called a “tail”.
Cosmos Cosmos is a term, ancient Greek in origin, that refers to the universe.
Eclipse An eclipse is when a celestial body is blocked from view by another celestial body. A common type of eclipse is a solar eclipse, in which an object (like the moon) obscures the sun.
Galaxy A galaxy is an entity that is bound by gravitational forces. Galaxies commonly consist of swirling masses of stars, planets, dust, gas, and dark matter. Our galaxy is known as the Milky Way.
Gravity Gravity is a force of the universe that attracts objects of mass to one another. On Earth, gravity pulls objects to its center; in our solar system, the sun’s gravity pulls the planets towards the sun’s mass.
Light-Year A light-year is a measure of distance. It is the amount of distance light can travel in a vacuum. One light-year is 9.46 times 10^12 kilometers.
Meteor A meteor refers to the light and particle of matter that enters the Earth’s atmosphere (from a meteoroid).
Meteorite A meteorite is the remains of a celestial body (a comet, asteroid, or meteoroid) that has collided with earth.
Meteoroid A meteoroid is a celestial body of rock or metal that is one meter in diameter or smaller.
Moon A moon refers to a satellite that revolves around a planet (i.e. orbits the planet).
Orbit The orbit is a reference to the direction, acceleration, and speed one (celestial) object takes in relation to another.
Planet A planet is a celestial mass that is large enough that it takes a round shape due to its own gravity. Planets are not large enough, however, to cause nuclear fusion reactions on their own.
Satellite A satellite is a natural or man-made object that typically orbits a planet.
Star A star is a round ball of plasma held together by its own gravity. Stars consist of burning gases and are luminous in nature.
Universe A universe refers to everything within the Cosmos — including stars, planets, moons, and galaxies.
Frequently Asked Questions
What are common terms in space exploration?
When venturing into the realm of space exploration, you’ll encounter various key terms such as “astronaut,” “rocket,” “gravity,” “satellite,” and “space station.” Astronauts represent skilled individuals trained to voyage through space, while rockets serve as the propulsive vehicles propelling both astronauts and their equipment into the cosmos. Gravity, on the other hand, is the fundamental force that draws one physical body toward another with mass. Satellites constitute human-made objects that orbit celestial entities, and space stations refer to habitable artificial structures positioned in space.
Can you name some space-related slang?
Certainly! There are several space-related jargons, such as “astro-chatter” for space or space travel discussions, “ground pounder” for those not working in space, “lunie” for a moon dweller, and “space case” for an absent-minded individual.
How do words relate to space and time?
In the realm of science and astronomy, terms like “spacetime,” “relativity,” and “continuum” are utilized to explore the connection between space and time. Spacetime is a blend of space and time, elucidating the movement of objects in space influenced by gravity. Relativity, especially Einstein’s General Theory of Relativity, provides a mathematical framework to comprehend spacetime and the gravitational impact on objects. The concept of “continuum” signifies the uninterrupted extension of spacetime, spanning the entire cosmos.
Which space words start with the letter T?
Below are some space-related terms beginning with the letter T: “telescope” (a tool for observing distant objects), “trajectory” (the route followed by objects like spacecraft), “terminator” (the line separating the illuminated and shadowed parts of a celestial body), and “transit” (when a celestial body moves in front of another, causing a light blockage).
