Explanation

• If a human-made (artificial) body moves around a celestial body it is called an artificial satellite.
• Artificial satellites are objects placed into orbit around celestial bodies by humans for purposes such as communication, weather monitoring, and scientific research.

Explanation

• If a celestial body moves around another large celestial body it is called a natural satellite.
• Natural satellites, like moons, orbit planets due to gravitational forces, distinguishing them from artificial satellites, asteroids, and planets.

Explanation

A satellite is an object that orbits a larger celestial body, such as a planet or star.

Examples:

• Moons (natural satellites) that orbit planets
• Artificial satellites (like the International Space Station) that orbit Earth

Explanation

• The nucleus is the solid, central part of a comet, composed of ice and rock.
• It is the source of the comet's activity, including the tail of gas and dust that forms when the comet approaches the Sun.

Explanation

• Vesta is the largest asteroid in the asteroid belt between Mars and Jupiter.
• It is believed to have a buried ocean 30 miles deep.
• It is thought to have a thin ocean with high salt concentrations.
• Vesta's surface is icy and rocky, with many craters and canyons.

Explanation

• The asteroid belt is a region of space where many small rocky bodies, called asteroids, orbit the Sun.
• It's also known as planetoids or minor planets.
• It is located between the orbits of Mars and Jupiter, spanning from about 2.2 to 3.2 astronomical units (AU) from the Sun.

Explanation

• Meteoroids are small rocky, stony, and metallic debris that orbit the Sun in various orbits and speeds.
• When a meteoroid enters Earth's atmosphere, it becomes a meteor, also known as a shooting star or meteors or fireballs.
• If a meteor survives its passage through the atmosphere and lands on Earth, it is called a meteorite.
