Determine the orbital radius for the extrasolar planets
Not what you're looking for?
Determine the orbital radius for the extrasolar planets x and y. Answers should be in astronomical units.
The planets are orbiting two stars with the same mass as our sun (1.9891 x 10^30kg). The planets are in two separate solar systems.
There are no other planets in either system and both stars are at a distance of 1000pc from earth.
planet X
mass/Me 12
Radius of stars orbit from centre of mass of the system/km 2 x 10^4
Orientation of the system - face on
Planet Y
Mass/Me 150
Radius of stars orbit from centre of mass of the system/km 2 x 10^3
Orientation of the system - edge on
