Definitions of Terms

For those of you that are scientifically declined, I have decided to give you a list of definitions for the terms above.

Sidereal Period-
The time it takes for a planet to make one revolution around its sun.

Orbital Velocity-
How fast a planet moves in its orbit around its sun.

Planetary Mass-
The size of a planet compared to that of the Earth.

Equatorial Radius-
The radius of the planet's equator.

Equatorial Diameter-
The diameter of the planet's equator.

Mean Density-
The average of the mass per volume of the planet.

Period Of Rotation-
The time it takes for a planet to make one complete spin.

Inclination of the Equator to the Orbit-
The planetary tilt, which causes the change in the seasons.

Albedo-
The fraction of incident light or electromagnetic radiation that is reflected by a planet or moon.

Mean Distance (AU)-
The average distance in Astronomical units from the planet to its sun as compared to the Earth.

Distance-
The distance by linear measurement from the planet to its sun.

Gravity-
The force of attraction that a planet has. (The force that keeps us on the ground).

Sidereal Day-
The length of the day on the planet.

Days in the year-
How many days are in the planet's year.

Atmospheric Pressure-
The pressure of the atmosphere at sea level.

Weight of the Air-
How much the air weighs.

Atmoshperic Contents-
What the atmosphere contains, (N₂ is Nitrogen gas, O₂ is Oxygen gas, and the other gasses are simply the other gasses in the atmosphere).
