in fact this is the solar system

Thats the best I can do to answer your question, hope it helped =)

My estimate is at least 100x the mass of the solar system, so assuming they took the sun, it would be 100 solar masses.

Well @LilRaspy, in most cases the star(s) are the most massive thing(s) in the solar system, because the sun for instance has the largest influence in the solar system. Without it, say, if Jupiter were more massive, it could disrupt the orbits of the main and dwarf planets. So assuming by the paths the solar system was stable and in that case, all you need to do is find a pulsar more massive than the star, because the star is probably the most massive thing here. So, we can definetly say its at least 2x more massive than the star. For more details ask them, because idk if they took the sun or a different star, and frankly, idk which pulsar they took either.

HOW massive is this system? And the pulsar?

oof

Pulsar are so exciting lol

Open this screenshot in fullscreen. They allow to double the size of a snapshot. You can too make the size x10 and he generate a very big pictures but not for steam. Great.
