# What would happen if the sun moved 7000 miles closer to earth? Would we notice a difference?

• That is LESS difference than the normal variation in distance than we get from the orbiting of the sun alone.

• No difference, the distance quoted would not harm us in any way. By the way why would the sun move?

• No, our distance varies by millions of miles in Winter/ Summer.

• No. Right now the distance from Earth to the Sun varies by about 3.1 million miles, from 94.5 million miles in July to 91.4 million miles in January. 7,000 miles closer would only be seven one-thousandths of one percent closer to Earth, at its closest point. 7,000 miles would make absolutely no difference to anything at all.

• Put it this way. If you were 2 metres from a log fire. You then move 0.1mm closer, would you notice a difference?

• It would probably cause Drought and Crop Failure

• That would be a difference of 0.0076% in distance, which would mean a 0.086% increase in solar radiation.

@oyubir: I recalculated. You are correct.

• Considering there's about a 3 million mile difference between the closest and farthest points of Earth's orbit from the sun, we wouldn't notice the slightest difference. Plus, if we were 7000 miles closer now, we'd be 7000 miles farther away in 6 months.

• No, it's not enough for there to be a noticeable change in climate but it would make the year about half an hour shorter, which would soon become noticeable.

• We wouldn't notice, although it could probably be measured with instruments... as it is now, the Earth's distance to the sun varies by about 3.1 *million* miles - we're closest in early January, and further away in early July (like, a week or two ago...) 7000 miles is a distance, but compared to the average 92,900,000 - it's not much.
