    [1]  2021/07/13 22:18   30 years old level / An engineer / Very /
    Purpose of use
    calculate orbital period / ground speed of a satellite for which I am adapting equipment
    [2]  2021/06/19 09:13   30 years old level / An office worker / A public employee / Very /
    Purpose of use
    Quicker than doing the math myself :)
    [3]  2021/06/10 06:49   50 years old level / A teacher / A researcher / Useful /
    Purpose of use
    To calculate the approximate spacecraft velocity for a CubeSat that we've built an instrument for (due to launch later this year), so that I can determine the approximate distance between measurements.
    [4]  2021/06/08 08:56   Under 20 years old / Elementary school/ Junior high-school student / Very /
    Purpose of use
    To build my own spacecraft.
    [5]  2021/06/04 03:19   Under 20 years old / High-school/ University/ Grad student / Very /
    Purpose of use
    Making an orbit simulation game
    [6]  2021/05/18 01:12   20 years old level / High-school/ University/ Grad student / Very /
    Purpose of use
    Making an orbital satellite array in Kerbal Space Program
    [7]  2021/05/15 23:38   - / High-school/ University/ Grad student / A little /
    Purpose of use
    to absolutely destroy the speed of light

    h = -6378.9999...999

    eventually, the flight velocity becomes
    1.9964981843217388711375066542006839330102944406138E+58922

    that's ~2 * 10^58922
    ... 10^58922

    a great way to replicate this would be type the base number
    -6378.13
    then copy and paste this sequence of 9's after the base number
    9999999999999999999999

    or even, copy the sequence created by pasting the above sequence... soon, there will be many 9's


    I have yet to hit a maximum or to see a visible approach to a limit.. but we know that -6378.14 is the symbol infinity...

    Suggetion is for someone to use python and beautifulsoup to approach the problem of finding the absolute largest number calculable on this calculator
    [8]  2021/05/11 10:37   20 years old level / High-school/ University/ Grad student / Useful /
    Purpose of use
    Used orbital parameters of a GPS satellite in space engine to see what the earth looks like from there.
    [9]  2021/04/29 03:09   60 years old level or over / An engineer / Useful /
    Purpose of use
    Checking speed and orbital rate of Starlink Satellites. Nice tool. :)
    [10]  2021/04/28 06:58   50 years old level / An office worker / A public employee / Very /
    Purpose of use
    Checking velocity required for geostationary orbit.
    Comment/Request
    Would love to see it available in imperial units as well as SI.
