Planets X, Y, and Z have circular orbits around a Star, which issimilar to our own Sun. Given the data listed below, answer thefollowing questions.
Note: \"Days\" are treated as \"Earth days\", thus having 24hrs.
| Name | Mass (kg) | Orbit Radius (million km) | Period (days) |
| Planet X | 5.82E24 | 143.8 | 356.9 |
| Planet Y | 7.53E23 | 458.5 | |
| Planet Z | 3.67E25 | | 114.8 |
a) Use the data for Planet X to calculate the mass of thisstar. Â
b) Use the data of of Planet Y to determine its period.
   Â
c) Use the data of Planet Z to determine its orbital radius.
