The idea of this game comes from

Newton's cannonball:

Thanks, Newton.

The result of the calculation is only an approximate value !

Value introduce:

1.The planet value is generated by algorithm criticism, in which the default is earth (173.7). Please click the question mark button beside it for other planet value. It is only used to control the correct circular motion of the bullet without affecting the calculation results.

2.When the gravitational constant (G) value is the default value, the planet mass (M) fills the 10^-21 times of the original value, unit is kg.

3.Planet diameter (R*2) is 0.1 times the original value, unit is km.

These data can be found on Wikipedia!

The calculation formula used is:
