Neptune
Neptune is the eighth and farthest planet from the Sun. It is a blue gas giant, similar in composition to Uranus.
Sun
The Sun is a star at the center of our solar system, providing light and heat essential for life on Earth through nuclear fusion reactions.
Full Moon
The Full Moon occurs when the Moon is fully illuminated, with its entire face visible from Earth.
Half Moon
A Half Moon occurs when half of the Moon is illuminated, creating a distinct semicircular shape.
Crescent moon
A Crescent Moon appears as a thin, curved sliver of light on one side, just after or before a New Moon.
New moon

In the context of space, an Alien refers to extraterrestrial life or beings from other planets.
Lunar
Anything related to the Moon is described as lunar, like lunar phases or lunar exploration.
Star
A star is a luminous celestial object composed of hot, glowing gases, producing its light through nuclear fusion.
Asteroid
Asteroids are small, rocky objects orbiting the Sun, primarily found in the asteroid belt between Mars and Jupiter.
Galaxy
A galaxy is a vast system of stars, gas, dust, and dark matter bound together by gravity, with the Milky Way being our home galaxy.
UFO
UFO stands for Unidentified Flying Object, an object in the sky that cannot be identified or explained readily.
Constellation
A constellation is a recognizable pattern of stars in the night sky, often forming imaginary shapes or figures.
Gravity
Gravity is the force that pulls objects with mass toward one another, keeping planets in orbit around the Sun.
Comet
