No. Earth's distance from the Sun is constant, and will remain so for billions of years.

It is possibly but it might not be. It's based on what you are believing and what you are read or watching on the news and such. If you really want to know more, try finding if scientist have posted up where or how far the Earth is from the sun, then try to get a telescope and calculate the distance between the Earth and the sun if the distance is different from when you have found the research or just check recent posts then you will know, either the Sun is getting closer to the sun or is the Earth getting closer to the Sun. I might be crazy or I just got into some weird scientific moment cause this is from a 13 year old kid that's just in 8th Grade so hope you find your answer and that this is helpful to you.

Yes and no. In Earth's orbit, it's distance fluctuates. You just so happen to ask this question not long after aphelion (farthest distance from the Sun), so yes, it will get (a tiny little bit, about 3 million miles, nothing by solar system standards) closer to the Sun until perihelion in January, and then start its journey away form the Sun, it does this every year. The Sun is losing mass, so its 'grip' on the Earth gets a tiny little bit weaker, so over long periods of time, the Earth is actually getting farther away from the Sun. Not to worry, the Earth's distance from the Sun changes so little over millenia, that won't be a factor in how hot or cold we are (there are other scary factors out there). The Earth is basically just orbiting the Sun, don't think of gravity like suction, think of it as falling. The Earth just so happens to be falling around the Sun, instead of into it, because its orbital speed keeps it from falling in.

There don't seem to be many people here actually thinking this through for more than a half second before making up their minds, so let me shed some light on the subject.

The Earth is not getting closer or farther from the sun in any abnormal way, and here's why:

Part 1, Orbit:
The Earth is in a constant orbit around the sun, meaning we will neverstop traveling through space, unless a mass equal to or greater than our sun enters the influence range of the sun and earth, which won't happen for a very long time.

Part 2, Gravity:
Since we have already established that the orbit will not change, let's talk about gravity. I bet you're thinking, "He can't know that for certain! We might be in danger any day now." Well, NASA is able to see millions of lightyears out into space, if something was headed towards us, we would know it probably thousand of years ahead of time.

Part 3, Temperature:
So, now we know that nothing in space is going to pull us out of orbit.
But even if there was, if we were getting closer to the sun, we would burn up in the course of about 6-8 months. Although the distance between the Earth and the Sun varies about 3 million miles in the course of a year, that is because the orbit around the Sun is not a perfect circle, It is a type of oval called en ellipse (I am only assuming that it is an ellipse. I know for certain that the Moon is in an ellipse-shaped orbit around the Earth, and I'm assuming it is the same with the Earth and Sun, but I am not 100% certain.) which is closer to the center in some areas. This varied distance is a major contributer to the transitions from seasons, Summer being closest to the sun, and Winter being farther from it. If the earth is thrown a mile away from its orbit, a large enough distance that it would be permantently closer year-around, the Earth would spiral out of control, sucked into the sun itself, the planet obliterated long before getting close enough to see a different from the surface. Likewise, if it was thrown farther away, enough that it enters the influence of another planet, most likely Jupiter or Saturn, it would most likely become unbalanced, crashing into that planet, creating a chain reaction, eventually destroying most if not all of our solar system.

Since neither of these has not happened yet, obviously, it probably won't happen any time soon.

That s not as easy a question to answer as you seem to assuming./ Earth s orbit is elliptical, not circular, so for half of the year Earth is getting closer to the Sun and for the other half Earth is getting farther away from the Sun in another sense, your statement is false, because the Sun is losing a prodigious

The Earth is on an elliptical orbit around the Sun and at the same time each year, we get closer to the Sun and then farther from the Sun. All the planets do.

We "slingshot" around the sun meaning as we get closer, we travel faster and then as we leave, we slow down again until the pull draws us back again.

Yes. Kind of.

Right now earth is headed towards its perihelion. That is the point in earths orbit that brings it closest to the sun but eventually, in northern winter, earth will swing by this point and begin heading towards the opposite point farthest from the sun, aphelion. That happens in northern summer.

Also the suns surface comes closer and closer to earth as the sun itself is expanding. The sun increases in diameter by about a meter per year. This rate is so slow, however, that we on earth will not feel any noticeable increase in sunshine for about a billion years.

The Earth as it gets closer to the Sun , it increases its orbital velocity. As the Earth approaches or recedes from the Sun it experiences mass changes. Hence a change in velocity indicates a change of mass.
The Earth's motion relative to our Galaxy goes thru an interaction between mass increases due to cosmic mass absorption and therefore expands its orbital radius.

The same scenario also takes place with Some Galaxies which are expanding their radius vector into space. Hence we observe it as Galactical recession ,Giving the appearance that the whole Universe is expanding its containment volume.

Technically, yes, it is, and has been since early July. The Earth's orbit is not perfectly circular, but slightly elliptical. As a result, we alternately come closer, then further away from the Sun. The closest point, known as Perihelion, occurs about the 4th of January, while the farthest point of our orbit (Aphelion) occurs about the 4th of July. At perihelion, the Earth is about 3.1 million miles closer to the Sun than at Aphelion.

Not that I've heard.
In any case, if sun and earth were approaching each other, it would be the earth moving closer to the sun - by changing its orbit.

Are you thinking that this might be the cause of global warming? No, it's been shown that the warming is caused by excess carbon emissions which are creating a greenhouse effect - they keep the heat from escaping into the outer atmosphere, and thus the earth's atmosphere warms up.

The earth isn't getting any closer to the sun. The only planet that is getting closer to the sun is Mercury. But the sun is actually slowly growing as hydrogen is converted to helium in it's core. But it isn't growing enough to contribute to global warming which as only come in to concern in the last couple centuries. Hope this helps. I verified all this information with my astronomy textbook.
