Very easy. We have a thing called spectroscopy. Different atoms and molecules absorb different wavelengths of light. We can see what the star emits and then see what happens to that light when the planet passes in front of that star. There are certain chemical signatures which on Earth are only known to exist due to the processes of life. Not everybody is necessarily on board with this hypothesis though, because it's entirely possible it is not a planet like Earth and those chemical signatures can exist in something like a gas giant.

As to the size of the planet, we have a pretty good idea of the size of the star and watching it over the course of a planetary year. We can see the deviation from its natural course by planets pulling on it and from that also estimates the mass of the planets.

124 Light Years is a serious distance and for some difficult to comprehend. In miles that 1,173,164,000,000,000 KM (728,933,719,760,000 Miles) even traveling at Light speed (670,616,629.3844 MPH). At 9.9 warp speed it would take 359.463 hrs upon arrival (15 day). Whow, it's difficult to fathom these numbers and makes a trucker who is 3 million miler look like a trucker can go more. But realistically, these is no way because of the traveling speed difference. This reminds me of that film 'Space Truckers' staring the late 'Dennis Hopper'.
