What is the distance from the surface of the Sun to the surface of the Earth?

This varies according to the location of the Earth in its orbit, because the orbit is not perfectly circular.
It varies from 147, 095,000 kilometers to about 152,100,000 kilometers. Both these and the semi-major axis of 149,598,023 kilometers (just under 93 million miles) actually represent the distance from the center of the Sun to the center of the Earth. The actual distance also depends upon which point of the Sun is chosen, and which point on Earth is chosen (one or both poles are normally farther away, but some points can be farther at some point in the year).
But if we use the perihelion, and subtract the equatorial radius of the Sun (which is 695,700 km) and the equatorial radius of the Earth (which is 6378 km), we get an "absolute minimum distance" of
147,095,000 - 695,700 - 6378 = 146,392,922 kilometers.* This would only be useful in such computations as the minimum Sun-to-Earth travel time for sunlight, which using this figure is
146,392,922 km /299792.458 km/sec = 488.3 seconds (8 minutes, 8.3 seconds).
*This distance could be temporarily reduced by solar prominences, which can extend up to 800,000 kilometers into space,

Does the distance from the sun affect the earth's temperature?
Because of the Earths atmosphere, the distance from the Sun, does not affect the temperature on the surface of the Earth. In the northern hemisphere, we are closer to the Sun in winter and the furthest away in summer.
How far is the earths moon from mercury?
Varying from the the distance from the Earth to the Moon + the distance from the sun to the earth + the distance from mercury to the sun, to the distance from the earth to the sun - the distance from mercury to the sun - the distance from the earth to the moon
Earth and sun distance?
The distance from Sun to Earth is about 150 million kilometers.
The phenomena occurring on the surface of the sun?
the surface of the sun is a phenomena for the earth surface from the sun
What pattern can you see between the serface temperature and the distance from the sun?
The surface temperature of the Earth is affected by many different factors. Although Earth's orbit alters the distance between the sun and Earth, the change in surface temperature is minimal compared to other factors. As evidence of this, consider the surface temperature at the poles, well below freezing at all times. Now compare this with the temperature in the tropics, where the temperature can be 60C higher than the poles. Consider also the change in temperature between night and day. Once again, there is a significant change in temperature with no significant change in distance from the sun. Factors such as cloud, wind and many other meteorological factors change the surface temperature more than the distance from the sun. However, we are able to say that the energy that reaches the Earth from the sun is reduced when Earth is further away from the sun. The amount of energy is inversely proportional to the square of the distance between sun and Earth.

What is is the earth distance from the sun?
An average of 93 million miles. It takes sunlight 8 minutes to arrive at the Earth's surface.
Is Astronomical Units from the Earth to the center of the sun or from the Earth to the surface of the sun?
It is the average distance between the centres of the two objects.
Distance from the earth?

Earth and sun distance?
The distance from Sun to Earth is about 150 million kilometers.
Which properties are most important to sustaining life on Earth?
distance from Sun, surface temperature, and atmosphere of oxygen
The phenomena occurring on the surface of the sun?
the surface of the sun is a phenomena for the earth surface from the sun
What would cause a decrease in the Earth's surface temperature?
In the winter, our part of the Earth tilts away from the sun, and another tilts towards it, that is why we have winter when, say, Australia has summer. As the Earth moves around the sun, its tilt is adjusted to the sun depending on where we are. (The distance of the Earth to the sun is also a factor.

What is the distance from sun to Earth in Au's?
An AU, or astronomical unit, is defined as the average distance from Earth to the Sun. Therefore, the distance from Earth to the Sun equals 1 AU.
An astronomical unit is the average distance between the?
One AU is the distance between the Earth and the Sun.
