One million miles is nothing in space.
Considering a light year is close to 6 trillion miles.
When it comes to stars, all that we see is a dot.
Build a bigger telescope, you can see a bigger dot...
It’s a great big universe
And we’re all really puny
We’re just tiny little specks

Re: A bigger dot
Any celestial body that has heat radiates light.
The entire spectrum of light - from radio waves to gamma waves - carries a vast amount of information about age, distance, speed, energy source, elements, state of matter, gravity, etc.
It is just basic science at the moment, little or no utility at the moment, but learning things about a universe we cannot currently visit is a good thing, and can ultimately benefit mankind more than it harms us.
