Bamma say there no point to Mercury. Bamma say it just get caught there. Bamma say without it Earths orbit would be closer to sun. Bamma say everything change. Bamma say you thank it for life on Earth. Bamma say it just a big hot rock. Bamma say no purpose at all. Bamma say so.

There is no point to any of this....
Sorry. Do you mean in orbit, or in general? In the orbit it is the perihelion, as previoulsy mentioned. If in general, then the equator on the equinox, and the tropics at each solstice.
The planet closest to the sun is Mercury, if that is what you meant, I don't know what the point of Mercury is, except maybe to befuddle newtonian scientists and provide a test for Einstein's big idea.
Here is some information on the planets:

In nautical astronomy, it is called the "subsolar" point. The point from which the Sun appears directly at the zenith.
If you know your distance from that point, then you know how far the Sun is from the zenith from your position.
Therefore, the navigator uses a sextant to determine the "zenith distance" of the Sun (actually, he measures the altitude over the horizon; the zenith distance is 90 degrees minus the altitude) and a compass to determine the direction. This gives the distance (and a rough direction) from the ship to the subsolar point.
Do this a few times throughout the day (with the known speed and heading of the ship) and you can find your position.

If you mean the PART of the planet closest to the Sun, that's the equator. If you mean where in it's ORBIT is it closest to the Sun, that's perihelion.

Perihelion is the name of the point in a planet's elliptical orbit closest to the Sun.

Your question would have some validity if you had identified the planet as well as the "point". So, what point on what planet are you talking about!

Either the North or South Pole depends on when it is summer or winter in the Northern Hemisphere.

depends on how the earth is turned on it's axis(meaning depends on the season)
usually it's the tropic of capricorn ( i think) that is closest....i get them confused the other one is tropic of cancer
