All of space, time, matter, and energy that exists, including all stars, planets, and galaxies.

: The leading scientific model explaining the origin of the universe from a massive expansion billions of years ago.

A massive system bound by gravity, containing millions or billions of stars, dust, and gas.

A gravitationally bound system consisting of a central star (the Sun) and the objects that orbit it.

Astro (Celestial Body):

Any natural physical body located outside Earth's atmosphere, such as a star, planet, moon, or asteroid.

A luminous sphere of plasma held together by its own gravity that generates energy through nuclear reactions.

A torus-shaped region located between the orbits of Mars and Jupiter, where most asteroids in our Solar System are found.

A vast region of icy bodies beyond Neptune's orbit, containing dwarf planets and minor objects.

Space Clutter (Space Debris / Space Junk):

Defunct human-made objects, fragments, or natural rocky debris floating in space

A disc of dust, gas, and rocks orbiting a star before consolidating into planets or moons.

Anything that occupies space and has mass; the physical substance of the universe.

The physical process in which a gas cools down and transitions into a liquid or solid structure, vital in early cloud and planet formation.

A solid piece of debris from an object (such as an asteroid or comet) that originates in outer space and survives its passage through the atmosphere to reach the surface.

: A small, icy celestial body that releases gases and dust as it travels close to the Sun

The transformation of liquid water into gas or water vapor when heated.

The layer of gases surrounding a planet, held in place by gravitational pull.
