Feb 2, 2016 · 3. Gravitationally, there is little immediate effect on earth on a daily basis, though over very long periods of time, stars that pass near enough to the sun could disrupt the orbits of Oort cloud objects and send them towards the sun (and earth or other planets in our Solar System).

Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them? 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. An animation of gravity at work. Albert Einstein desc...
Gravity is what holds the planets in orbitaround the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light. Albert Einstein ...
Gravity is very important to us. We could not live on Earth without it. The sun's gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun's light and warmth. It holds down our atmosphere and the air we need to breathe. Gravity is what holds our world together. However, gravity isn’t the same everywhere on Earth...
Jul 23, 2019 · The life and death of stars form the ingredients that make up Earth, making stars critical to life as we know it. The early universe contained nothing but the chemical elements hydrogen, helium, and tiny amounts of lithium and beryllium. During their life cycles, stars create elements with low atomic masses. These are the first 26 elements in ...

How do stars affect our culture?
After a supernova, some stars leave behind a super dense neutron star, while the heaviest stars leave a black hole. Based on our understanding of stellar evolution, the Sun will start to run out of core hydrogen in about 5 billion years. The Sun will expand, engulfing several of the inner planets, including Earth.
