Comets, asteroids, and meteors are celestial bodies in our solar system. Comets are icy bodies that release gas and dust, creating tails as they approach the sun. Asteroids are rocky, often found in the asteroid belt between Mars and Jupiter. Meteors are flashes of light from meteoroids entering Earth’s atmosphere.

Black holes are regions in space where gravity is so strong that nothing, not even light, can escape. They are formed when massive stars collapse in on themselves. Black holes have a boundary called the event horizon, beyond which nothing can escape their gravitational pull.

The Kuiper Belt is a region of the outer solar system beyond Neptune that is home to thousands of small icy bodies, including dwarf planets like Pluto. It is believed to be a remnant of the early solar system and provides valuable insights into its formation and evolution.
