RJup is the radius of Jupiter. 1 MEarth is equal to one million times the mass of the Earth. I’m not sure about RV limits.

1 MEarth is 1 Earth mass. Even our sun is only a third of a million Earth masses. Jupiter is about 318 Earth masses.

...so it's got a mass 3x that of our sun, but it's the size of Jupiter? And it's a planet? ...What? The star it orbits is about the same size as our sun, yet a planet orbits it with 3x the mass? I'm missing something massive here, or the summary is terrible.

The M in this context stands for "Mass" not "Mega."

If you take a look at the linked PDF you'll see that the "Earth" portion of that term is a subscript, so it reads "90-150 Earth masses."

> not sure about RV limits

Radial velocity, how quickly a planet moves “back and forth towards an observer” as it revolved about its star [1]. Its amplitude suggests planetary mass, its spectral shape orbital eccentricity.

I made a mistake here on MEarth and didn't notice the correction until well after the update window on my comment, oops!
