Is Reya's Tear (star in the Rosharan night sky) the bigger star in the Taldain system?

[Atreides]

I am rereading the Stormlight Archive and caught the mention of The Tear, a star in the Rosharan night sky that is named after Reya.  With how connected everything is in the Cosmere I thought that maybe that star would have some significance, like the sun of one of the other shardworlds.  Even though Taldain is inaccessible to the rest of the Cosmere, could The Tear be the bigger sun in the Taldain system?

I have no Idea, but that thought gave me an idea. What if we've seen Reya's tear before? If so, this would mean that the planets are close enough for star travel, which fits the 6th of Dusk theory that the people are from MIstborn Era 3.

 

One way to find out your question is to ask 2 questions of Brandon

A) How big is Cosmere standard? In Arcanum Unbounded, Khriss describes the systems, and says they're ___ Cosmere standard (e.i Roshar is 1.7 [made that up] Cosmere standard)

and

2) How  far away is Reya's tear from Roshar?

 

Using some advanced math, you could, technically, find out how big Reya's tear is, and then compare that to Khrisses map of the Taldain System to find out if they're a similar size. The only problem would be if her maps aren't to scale.

Cosmere standard is in relation to the planets specifically. Cosmere standard is yolen/scadrial which is equivalent to earth. So Roshar is 0.7 our gravity and 0.9 our size, and so forth for the others. 

And the Cosmere is a dwarf star cluster, with many of the same stars in and out of the Cosmere. Taln's scar on Roshar, and the Red Rip on scadrial are the same cluster of red stars. 

The stars in the Cosmere avg. Roughly 50 light years apart... And Era 4 is planner as a full on Space Opera.
