Stars Passing Close to the Sun

If a star were to pass in between the earth and the sun ... it would be bad.

I’ll be 61 next month, with a billion things to worry about before I worry about a passing star, but I’ll put it on my list.

Speaking of a star here or there for a steller close encounter is one thing, but....

What about a trillion star encounter? Such WILL happen, with Andromeda galaxy and the Milky Way making a beeline for each other. One trillion stars will “collide” with the 100 billion Milky Way stars.

Timeframe for any concerned.... About 3 billion years.

"Stars Passing Close to the Sun"

Sounds like an Obama fund-raising bash in Tinsel Town.

As I see it, everything in that article, plus $1.50 will get you a cup of coffee most places besides Starbucks.

The galaxy is nothing more than a giant bumper car track and one day the ride will be over.

Further analysis will be needed using upcoming Gaia data

We'd better be nice to the Erf so Gaia is willing to give us her data ....

Bad, but also very unlikely. The nearest star is 4 and a quarter light years from us, so coming within earth-sun distance would be like shooting a beer can from 15 miles away.

Pretty interesting stuff. I hadn’t heard about the close approach of Gl710. Unfortunately, I won’t be around to make observations.

The Sun is a star. But if one did pass between Earth and our sun, yeah, it would be very, very bad.

i’ll be 61 next month

I agree with you, I'm 75.

I didn’t know stars were going in the “wrong” direction. I thought with the big bang everything was expanding? Unless it is traveling from the center going faster than our system. Sorry if I sound confused, just not visualizing how this is happening. I’m a visual learner.

[Does so]

Timeframe for any concerned.... About 3 billion years.

Excuse me? But did you say that'll be 3 million or 3 billion years?

:)

Actually, it might be 4...

Here is what the night sky might look like as it gets closer. Oh, there is no escaping it... Andromeda is pulling us closer to it, while we (Milky Way) pull Andromeda closer to us.
