a planet's orbital period. based off kepler's 3rd law (Wrong.)
The planet's orbital radius. (Correct.)
the properties that the sun has in common with other stars is that its made of hot gases and is also a star
This is a hard question but stars have their own personality and are all different

Long-lived stars begin their lives with less mass and a smaller amount of hydrogen fuel. and Long-lived stars are less luminous during their main-sequence lives.
what is the term used for the orbital period of an object with respect to the stars?
Yes, by measuring both the stars orbital period and its change in velocity over the orbit.
A black hole can be inferred by tracking the movement of a group of stars that orbit a region in space which looks empty
Moon's orbital period . . . With respect to the distant fixed stars . . . 27.32 days With respect to the sun & the phases of the moon . . . 29.53 days

Astronomers use the term "sidereal period" to describe the time it takes for a planet to orbit the sun relative to the stars. Sidereal periods are measured based on the apparent motion of a planet against the background of fixed stars rather than against the sun. This allows for more precise measurements of a planet's orbital period.
