# What is the closest candidate for Dark Matter currently?

I've both fascinated and frustrated after learning about the existence of Dark Matter.

Can we find evidence of Dark Matter within our Solar system? What is currently the closest candidate for Dark Matter?

• You are asking about two very different things "Dark Matter" and "Dark Energy". Apart from the word "Dark" they are not really related. Please split into separate questions, and be sure to explain what prior research you have done on each question. – James K Sep 7 '18 at 22:13
• @JamesK Oh I asked based on the fact that dark matter and dark energy are manifestations of the same dark "thing". Thanks for your suggestion. – Dan Jay Sep 7 '18 at 22:18
• I'm voting to close, as sub-questions 1 & 2 are substantially different and therefore the overall question is too broad. There are multiple candidates for dark matter so I also think #2 invites opinion-based answers. – Chappo Hasn't Forgotten Monica Sep 8 '18 at 0:53

This arxiv post says if there is dark matter in the solar systems, its density should be below $\approx 1.4\cdot 10^{-20} \frac{g}{cm^3}$.
Note, it is a negative result, i.e. they didn't find anything, but they are suspecting, if the dark matter density would be at least $\approx 1.4\cdot 10^{-20} \frac{g}{cm^3}$, they had found it.
