python new test frameworks

Completing harder katas makes you a better problem solver.

I think you should add another radii for the second satellite, otherwise good problem I like the physics ones!!

Sometimes random tests result is suspectible to floating point errors:

meetingTime(45, 37, 1)
expected '208.12' to equal '208.13'

If a satellite has a velocity greater than orbit velocity in its gravitationaly bound syatem, then its mean orbital radius will increase. In order to have circural orbit your initial tamegntial velocity must be exactly equal to the orbit velocity for your altitude - else the orbit is eliptical. Are we meant to use orbit velocity equations in this kata?

Different initial speeds.

How can two objects be in circular orbit at the same radius and have different speeds?

I'm Agree with your opinion, I just saw this five minutes ago and I just can't figure out of this.

This is completely wrong. If Ta == 0 or Tb == 0 that means it takes 0 second to make a full orbit, meaning they are going infinitely fast, meaning the answer should be 0 or Error depending on how you interpret it. But the answers act as though when Ta == 0 or Tb == 0, that means that A or B isn't moving at all. That goes in direct opposition to what you say in the description.
