The subject of what is gravity encompasses a wide range of important elements. | NASA Space Place – NASA Science for Kids. The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. In this context, an animation of gravity at work.
Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet. It’s a balance of gravity pushing in on the star and heat and pressure pushing outward from the star’s core. Equally important, when a massive star runs out of fuel, it cools off. Gravity is the force by which a planet or other body draws objects toward its center.

explore How Do We Weigh Planets? We can use a planet’s gravitational pull like a scale! A galaxy is held together by gravity. Our galaxy, the Milky Way, also has a supermassive black hole in the middle.
When you look up at stars in the night sky, you’re seeing other stars in the Milky Way. If it’s really dark, far away from lights from cities and houses, you can even see the dusty bands of the Milky Way stretch across the sky. All About Neptune | NASA Space Place – NASA Science for Kids.
The coldest planet in our solar systemNeptune is dark, cold, and very windy. From another angle, it's the last of the planets in our solar system. It's more than 30 times as far from the sun as Earth is.
Neptune is very similar to Uranus. It's made of a thick fog of water, ammonia, and methane over an Earth-sized solid center. Its atmosphere is made of hydrogen, helium, and methane. Another key aspect involves, the methane gives Neptune the ... GOESboardgame back - NASA Space Place.
The other two are the Sun and Earth's own rotation. Furthermore, the Moon's gravity creates a high tide every 12 hours and 25 minutes. Low tide occurs midway between each of these two high tides.
