More generally escape velocity is the speed at which the sum of an objects kinetic energy. 21744 kn at the surface.
How Long Does It Take Sunlight To Reach The Earth
As objects travel faster and faster they get heavier and heavier the heavier they get the harder it is to achieve acceleration so you never get to the speed of light says roger rassool.
How fast does light travel to earth from the sun. The first of gordon woodcocks methods of interstellar travel is go slow. Earth wouldnt just drift into space instantly. The escape velocity from earth is about 11186 kms 6951 mis.
Distance between stars is huge traveling said distance slower than light will take a huge amount of time human beings have a very limited lifespan. In physics specifically celestial mechanics escape velocity is the minimum speed needed for a free object to escape from the gravitational influence of a massive body. In a heliocentric frame non rotating with respect to stars light travels in a straight line hence this is a perfectly inertial frame.
However in this frame earth does not travel in a straight line hence the geocentric frame is non inertial. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the sun to the earth. From our vantage point some 25000 light years from the galactic center the sun speeds around in an ellipse making a complete revolution once every 220250 million years or so.
In a geocentric frame non rotating with respect to sun the moon speeds up when it heads towards the sun and then slows down by the same amount when it. Imagine the sun vanished right now. If the sun suddenly disappeared from the universe not that this could.
Sunlight takes about 8 minutes 17 seconds to travel the average distance from the surface of the sun to the earth. If you looked out at the sun across the 93 million miles of space that separate our world from our nearest star the light youre seeing isnt from the sun as it is right now but rather as it was. The speed of light in a vacuum is 186282 miles per second 299792 kilometers per second and in theory nothing can travel faster than light.
