The dot-product and cross-product are used in high order physics and math when dealing with matrices or, for example, the properties of an electron (spin, orbit, etc.).

It is FLAT. It continues in all directions even if it is broken by something physical. It does not have to be physical. To imagine a geometric plan put a ruler on a pencil and spin it.
Yes, Mercury does rotate about its own axis. However, its rotation is unique in that it is in a 3:2 spin-orbit resonance, meaning it rotates on its axis three times for every two orbits around the Sun.
Mercury to orbit around the Sun; a typical year on Mercury would take 88 Earth days. Because of Mercury's ever changing distance from the sun and its 3:2 spin-orbit resonance the temperature on Mercury's surface is complex and varied.
Mercury has a very slow rotation on its axis, taking about 59 Earth days to rotate once. This means that a day on Mercury is longer than a year on Mercury. Its rotation is also unique in that it is in a 3:2 spin-orbit resonance, resulting in strange patterns of movement.
Mercury has a relatively slow rotation compared to its orbital period, resulting in a 3:2 spin-orbit resonance. This means that it rotates three times about its axis for every two orbits around the sun. As a result, a day on Mercury (from one sunrise to the next) is about 176 Earth days.
It takes about 58.6 Earth days.
An orbit is where something spins and goes in a circle, a spin is just a spin....
yes, mercury does spin counter clockwise.
Because of the periods of Mercury's orbit and spin, a year (complete orbit around the sun) on Mercury is about 88 Earth days long, while a day (time for the Sun to appear in the same place in the sky) is twice that length, at about 176 Earth days long.
This used to be believed, but we now realise it is not so. Mercury rotates 3 times for every 2 orbits of the Sun.
Yes, Orbit Helios does spin. I recommend him, because he spins very well :)
If by spin you mean "rotate daily" then yes. But you could refer to our "orbit" as a spin around the sun. But if you want to refer to "spin" as any oscillatory/periodic motion of the earth, then we spin around our central axis, we orbit around the sun, we precess the rotational axis around a precession axis, our obliquity oscillates periodically and our eccentricity oscillates around the foci of our elliptic orbit which is near the center of the sun. These characteristics of our orbit are known as the Milankovic cycles.
Mercury is the fastest planet in our solar system, with an average orbital speed of about 47.87 km/s. Its close proximity to the Sun causes it to travel quickly along its orbit.
