Answer
given,
diameter of planet = 1.8 x 10⁷ m
radius of planet = 0.9 x 10⁷ m
time period = 22.3 hours
the planet orbits 2.2 x 10¹¹ m period of 402 earth days.
acceleration= 12.2 m/s²
we know
M_p = 1.48 x 10²⁵ Kg
b) Formula to calculate the mass of star
M_s = 5.22 x 10³³ Kg
There are 88 constellations
