You use Newton's Gravity Theory, GM/r = v^2. Then Earth mass M = rv^2/G = r^3w^2/G or M= r(2pi r)^2/GT^2
the max distance from earth to sun is known as aphelion
The average distance of a planet to the sun is the Semi-major axis. The furthest it gets is the Aphelion and the closest it gets is its Perihelion. The Sun to Earth Distance is also known as one Astronomical Unit (AU).
On average it is around 93 million miles. The earth-sun distance is known also as 1 astronomical unit, or one AU. (149,598,000 kilometers) The Earth orbits in an elliptical path around the Sun, with an average distance of about 93,000,000 miles.
No such planet is known, but it is known that Mercury has a rotational period of 58 days and Venus has a rotational period of 243 days.

Not sure what you mean with "known as"; there is no special name for this distance, if that's what you mean.
I suspect that is not known. It is hard to determine the period of rotation for a star that is about 700 light-years away.
That is known as an "astronomical unit".
This is known as the `Perihelion`, for Earth it is 147,098,290 km or 91,402,641 miles
The length of a day on Neptune, also known as its period of rotation, is about 16.1 Earth hours, or 0.67 Earth days. The length of a year on Neptune, also known as its period of revolution, is 164.8 Earth years, or 60,190 Earth days.
Neptune has 13 known moons and an orbital period of about 60190 Earth days.
The period to rotate once on its axis is known as a day,The period to revolve around the Sun is known as a year.

The method of using specialized instruments and geometry to determine distance and elevation of specific areas is known as surveying. Surveying is used to build roads and to establish property lines of real estate.
