2. The streak of light seen when a meteoroid (a small piece of rock or metal from space) enters a planet’s atmosphere and burns up due to friction/heat.
4. A very large system of stars, stellar remnants, interstellar gas, dust and dark matter, bound together by gravity.
5. The planet known for its beautiful rings (6 Letter)
6. The force that keeps planet in orbit (7 Letter)
9. System A star and all the objects bound to it by gravity: planets, moons, comets, asteroids, dust and gas.
11. Way Our galaxy’s name (8 Letter)
12. All of space, time, matter, energy and the physical laws and constants that govern them — everything that exists.
