What could possibly happen if Earth is at least 10\% closer to the sun?

The closer you are to the sun, the hotter the climate. Even a small move closer to the sun could have a huge impact. That’s because warming would cause glaciers to melt, raising sea levels and flooding most of the planet. Without land to absorb some of the sun’s heat, temperatures on Earth would continue to rise.

How close can the Earth get to the sun without burning?

The sun is about 93 million miles away from Earth, and if we think of that distance as a football field, a person starting at one end zone could get about 95 yards before burning up. That said, an astronaut so close to the sun is way, way out of position.

Do light rays bend when they enter the Earth’s atmosphere?

Light rays that travel straight down do not bend, while rays that enter the Earth’s atmosphere at a shallower angle get refracted and bend towards the normal, roughly following the direction of the Earth’s curvature.

Why are the rays of the Sun and the Earth so different?

Now, the Earth is larger than a point, and the Sun is larger than the Earth, so the average of all the rays that leave the Sun and hit the Earth actually converge, but because the Earth is so small and so far away (i.e. it subtends a very small angle from the Sun) the rays are almost completely parallel,…

How do you find the direction of the sun’s rays?

First, find the distance in degrees between the latitude of where you are and where the Sun’s most direct rays are shining on Earth at that time of year. Then subtract that number from 90°. The most direct rays of the Sun are shining at: • 23.5°N on the summer solstice • 0° (the equator) on the equinoxes

How does atmospheric refraction affect the Sun?

Atmospheric refraction makes the Sun visible even when it is just below the horizon. This effect is especially powerful for objects that appear close to the horizon, such as the rising or setting Sun, because the light rays enter the Earth’s atmosphere at a particularly shallow angle.
