While I am far from being a expert on this subject. I do have interest in this. But I do not know a lot about this as current time. But I plan to make improvements to my space knowledge with time. For me space is important. Because what is out there, and it is a fact that future of the human race lies on what we are going to learn about space in the coming years and decades.
I do not yet know properly what I am going to write about here. But it is going to be about space. Weather it is close or distant from Earth or our solar system. To start with I am going to write about few interesting close starts that are less then 10 light years from our solar system.
Our closest neighbour in space is Alpha Centauri.
That star system has two sun. One yellow (G2 V type) and one orange type of star. Currently it is not known if there are any planets orbiting around this stars. There is also a third star named Proxima Centauri. But that is a red dwarf star, class M5.5Ve according to measurements. It might have planets, but is unlikely to host any life on planets around it.
What ever is in Alpha Centauri is it a interesting star system in my opinion. Worth more studying and observation.
This star is according to measurements younger and larger then our own sun. The white dwarf is a remnant from a exploded star that once was in this star system. Recent measurements there is a lot of dust in this star system. It is assumed that it is mostly from the sun that did burn out. But it might well be that there is a dust from other original gas cloud that did form this star system. But that has not yet been confirmed today, far as I know.
There is more to be learned on what is out there. But this is just a first about our closest nearby stars. But I have interest in those starts, since I want to know if there is anything else around them. But might not have been detected yet by the human race.
Here is a map of nearby stars close to our solar system.
