Constellation
A pattern or shape formed by a group of stars. Constellation. In simple terms, a constellation is a group of stars in the sky that form recognizable shapes or patterns and are used in astronomy to identify areas of the night sky.
Galaxy explained in an easy to understand way.
Galaxy
A massive system of stars, gases, and dust held together by gravity. A galaxy is a huge collection of stars and other matter bound together by gravity.
Gravity explained in an easy to understand way.
Gravity
The attractive force between all objects that have mass. Gravity is the force that pulls objects toward each other, like how Earth pulls us down.
Light year explained in an easy to understand way.
Light year
The distance light travels in a year 9.5 trillion km. light year. A light year is a unit of distance that measures how far light travels in one year in space.
Meteor explained in an easy to understand way.
Meteor
A streak of light created when a meteoroid is heated by Earths atmosphere. Meteor. A meteor is a bright trail of light in the sky caused by a space rock burning up as it enters Earth's atmosphere.
Moon explained in an easy to understand way.
Moon
A natural body that revolves around a planet is called a moon. Moons are celestial objects that orbit planets, like how our Moon orbits Earth.
Moon phase explained in an easy to understand way.
Moon phase
Changes in the shape of the moon as seen from Earth. Moon phase. Moon phase is the different shapes of the moon we see from Earth as it orbits around us.
Orbit explained in an easy to understand way.
Orbit
The path of one body around another, like Earths orbit around the Sun. Orbit. An orbit is a regular, repeating path that an object in space follows around another object due to gravity.
Planet explained in an easy to understand way.
Planet
A large body that revolves around the Sun or star. A planet is a big round object in space that orbits a star like our Sun.
Revolution explained in an easy to understand way.
Revolution
The motion of one body around another, like the Earth around the Sun. Revolution. It is the circular or elliptical movement of one object around another, often seen in planetary orbits.
Rotation explained in an easy to understand way.
Rotation
The turning of a planet on its axis. Rotation. Rotation is the spinning of an object, like a planet, around an invisible line called an axis.
Satellite explained in an easy to understand way.
Satellite
An object that moves around a larger object in space, like the moon around Earth. Satellite. A satellite is an object in space that orbits another larger object, like a planet.
Solar system explained in an easy to understand way.
Solar system
A group of planets and other objects that revolve around a sun. Solar system. The solar system is a collection of planets, moons, and other bodies orbiting our star, the Sun.
Star explained in an easy to understand way.
Star
A huge ball of very hot gases, like the Sun. A star is a massive, glowing sphere of plasma that generates energy through nuclear fusion in its core.
Supernova explained in an easy to understand way.
Supernova
The bright explosion of a dying super giant star. Supernova. A supernova is a powerful burst of light and energy that happens when a massive star explodes at the end of its life.
Tide explained in an easy to understand way.
Tide
The daily rise and fall of the water level in the oceans. Tide. Tide is the movement of ocean water caused by gravitational forces from the moon and sun.
Universe explained in an easy to understand way.
Universe
Everything that exists, including the stars, planets, and energy. Universe. The universe is all of space and everything in it, from the tiniest particles to the vast array of galaxies.
