They are centre to centre, but given the relative measures and the fact that the distances are averages over elliptical orbits rather than circular ones, the difference between the two is irrelevant.
The amount of substance of a planet is measured in kilograms, a unit of mass. In this sense, there is no difference between one planet and another. It doesn't make much sense to speak about the "weight" of a planet, but you can measure the attraction between a planet and another object in units of force, i.e., in Newtons.
Our planet is measured in miles (diameter)
Mass is measured in Kilograms (kgs) or Pounds Weight is measured in Newtons there is a difference between mass and weight because weight depends on gravity, mass does not. So you weight changes depending on which planet you are on. Weight W masss m gravitational accelearation g W = mg
Astronomical Units (AU) are most useful in describing the distance from a planet to its sun. For just about any other purpose they're either too long (distances on a planet's surface) or too short (distances between stars) to be of much practical use.
Only if the two masses are at different distances from the planet's center, or on planetswith different masses.If the two masses are at the same distance from the same third mass ... or just attractingeach other with any separation distance, then no.
distances are greater between outer planets

No. Short distances (the width of a planet) are measured in kilometers. Distances from one place to another in our solar system are measured in Astronomical Units (AU), one AU being 93 million miles. Longer distances outside our solar system are popularly measured in light years, Alpha Centauri is 4.2 light years away, for example, but note I said "popularly". Astronomers use the term "parsecs" when speaking of interstellar distances (one parsec is 3.26 light years).
The Sun is many thousands of times closer to Earth than any other star.
The difference is approx 660 Celsius degrees.
Normally in Astronomical Units (AU) which is the average distance from the earth to the sun.
The center of the planet is called the "core."
Different units of measurment are used because the distances involved are very different. A planet's diameter or circumference is measured in miles or kilometres because that is quite manageable (for example: 20,000 miles). The distance between planets is much greater so is usually measured in light years (the distance light travels in one year = 9,460,730,472,580.8 kilometres) or, for really extreme distances, in parsecs. (1 parsec = approx 31,000,000,000,000 kilometres). There is also the Astronomical Unit (AU) = 149,597,870.7 kilometres.
Mount Chimborazo in Ecuador's Andes Mountains is the furthest point on land from the Earth's center due to the bulging of the planet around the equator. This feature is measured from the center of the Earth rather than sea level, making Chimborazo's summit the highest point on Earth when measured from the Earth's center.

Newton's law of universal gravitation states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This means that gravity depends on both the mass of the planet and the distance between the planet and the object experiencing the force.
