Overview

Your first task is to create a program to calculate the properties of motion of a satellite $($this being any celestial body in orbit, not just manmade spacecraft$).$ This motion is described by the formula $v=2\frac{r}{T},$ where $v$ is the velocity$/$speed in $k\frac{m}{h},r$ is the orbital radius in km $,$ and $T$ is the time for one orbit in hours. $($Note: While NASA uses $15$ digits of $,$ you should use $=3\mathrm{.}14$ for this assignment, i$.$e$.,3$ digits only.$)$

Create a program in your source directory src named

Ask the user for an input of $v,r,$ and $T,$ in that order.

The user will provide a placeholder value of $-1$ for the value they wish to calculate, and values $>0$ for the other two. Any input that does not match this format is invalid and should be handled appropriately.

You will calculate the desired value using the formula above and display it rounded to two decimal places. You do not have to round the value stored, just the printf output.

If any of the $3$ measurements is close to a known object, print

$[$measurement$]$ is close to that of $[$object$]$

If this is the only matching measurement, print

However, this is likely not $[$object$]$

If any $2($or $3)$ measurements match, print

This object is likely $[$object$]$

The following ranges are considered "close" to the three known objects, Earth, Moon, and International Space Station:

Earth

$r$:$148-151$ million km

$T$:$8700-8800h$

$v$:$100-110$ thousand $k\frac{m}{h}$

Moon

Moon

$r$:$360-400$ thousand km

T: $624-672$ hours

$v$:$3600-3800k\frac{m}{h}$

International Space Station

$r$:$6700-6900km$

T: $1\mathrm{.}4-1\mathrm{.}6$ hours

$v$:$26-30$ thousand $k\frac{m}{h}$

Print in the following order:

all measurements that are close: $r,T,v$

all objects that have at least $1$ match: Earth, Moon, International Space Station
