Test Case: New Intrasystem Surveys

Intrasystem surveys are completed by vessels as they approach the target star system, usually within the Oort orbit of that system. The survey takes 1d10 days, usually to the maximum length when there are indications of additional planetary bodies not fully identified. The ship typically does not need to enter the system in order to complete the survey.

4. Intrasystem Survey – 1d10 days (Part 1)

A. Main Sequence Stars	Roll for number of planets:
O (Blue)	none
B (Blue-white)	3d6
A (White)	3d6-1
F (Yellow-white)	3d6-1
G (Yellow)	3d6-2
K (Orange)	3d6-2
M (Red)	3d6-2
B. UV Sequence Stars	Roll:
	3d6/2 (and all are charred rockballs)
C. IR Sequence Stars/Blackholes	none

Part 2: Bode's Law

Bode's Law is a hypothesis that the bodies in some orbital systems, including Sol's, orbit at semi-major axes in a function of planetary sequence. In other words, it can be used to determine how far out from a star each planet would orbit.

Step 1: The first orbit lies at a distance of (1d6*0.1) astronomical units (AU) from the star, regardless of star class. Therefore, around any given star, the first orbit could lie anywhere from 0.1 to 0.6 AUs from the center of the star's mass. This distance (D) is also used in determining the orbital distances of all other planets.
