Do the sun's rays stay at the same temperature when they reach the earth?

In the case of Earth, the distance between the closest and the farthest point doesn't vary much; from the Wikipedia, at periapsis (closest approach), the distance is 147,098,074 km, at apapsis, 152,097,701 km; that makes a difference of 3.4%.

Wiki User
∙ 13y agoNope - it follows an elliptical path rather than an exact circle. The average distance is approx 93,000,000 miles. Earth is closer to the sun during the northern hemisphere's winter (early January) and furthest away in July.

∙ 14y agoMore or less, but not entirely. All planets move around the Sun in elipses; the Sun is at one of the elipse's focal points. In the case of Earth, the changes in distance to the Sun are not very significant; for example, the seasons are caused by the tilting of the Earth's axis; the effect of the varying distance to the Sun is negligible.
Wiki User
∙ 6y agoNo, the distance does change a bit.
The Earth's orbit is almost a circle, but it's actually an ellipse.
Wiki User
∙ 13y agoNo, it ranges from 147,098,074 km to 152,097,701 km. Curiously, the Earth is closest to the Sun in January, and farthest away in July.
Wiki User

No, it varies slightly.

No, it varies slightly.
Wiki User
∙ 13y agoNo. Earth moves in an ellipse around the Sun; at one point of the orbit (currently in January) it is closer to the Sun, at another point it is farther from the Sun.
Wiki User
∙ 8y agoNo, the Earth's orbit is an ellipse rather than a perfect circle, and the Sun is about 3% closer to the Earth in January than it is in July.

How is absolute zero originally determined?
The volume of gases decreases with temperature; extrapolating the volume/temperature relationship, it looked as if all gases would reach a volume of zero at approximately the same temperature, about minus 273 degrees centigrade.
Which would be the first to reach Earth if a light signal and a radio signal were emitted from a star?
It would be a tie; both light and radio are electromagnetic waves, as are X-rays, gamma rays, ultra-violet and infrared. They all travel at the same speed, the "speed of light", which is about 300,000 km/second, or 186,000 miles per second.
Does the radiation emitted by earth's surface have longer or shorter wavelengths compared to solar radiation?
because they do not go to the same direction e.g the short-wave radiation heats the earth and the long-wave radiation heats the atmosphere.
If earths albedo was higher but earth was farther from the sun could the earth have the same temperature?
No, both conditions would make the earth cooler.
Why do w have different temperature at the same time in different parts of the world?
since the rays of the sun hit mostly the middle of the earth that is the equator known as the main area of the ITCZ (inter tropical convergence zone ) ,that is the area that will receive most of the heat and dude to the earth's rotation winds are created which are the cause of the so called trade winds they carry winds towards the poles of the earth other factors are responsible for the distribution of heat but sun rays mostly reach the middle and outer middle of earth which is mainly responsible for the equator and regions closest to it to be hottest areas and the poles colder
How can you prove that the earth is moving around the sun?
if it's not the sun rays won't reach different places in the same time
Does gama rays reach earth?
A few of them do. Gamma rays are the same as x-rays, only with such higher frequencies than they have a special name. Fortunately for us, our atmosphere is opaque to all but the really powerful ones.
Why does the earth not reach the same temperatures as the moon?
because of the temperature of the atmosphere, they are in different places, the temp of the atmosphere is different.
What happens to the temperature as the angle at which the Sun's Rays strike earth's surface increases as the angle decreases what happens to the length of shadows at the same time?

Is Reach larger then Earth?
No, reach is about the same size, notice that reach is full of craters, so it has a different atmosphere to earth.
Why does the area around the equator stay the same temperature year-round?
Because the Earth is tilted on it axis and the equator is the bit closer to the suns rays then anywhere else!!!!!!!!!!!!!!
What is the temperature of the inside of earth?
The same temperature as the rock in which it sits (the aquifer).
Does mars have the same temperature as earth?
No, its colder.
Is the average temperature on earth always the same?
Unfortunately the average temperature of the Earth is increasing. See global warming.
WHAT IS THE temperature of water inside earth?
The same temperature as the rock in which it sits (the aquifer).
What causes the different seasons on the earth?
Earth has seasons because its axis is tilted. Earth's axis is always pointed in the same direction, so different parts of Earth get the Sun's direct rays throughout the year.
