Apparently Gleise will pass close enough to be seen with the naked eye. About 3 times as bright as mars. Probably a bit too early to get excited about it.

It won't be Geise's brightness more so than Mars - that is the worry. It's the 'gravitational' effect on our solar system that is the worry. Imagine earth pulled from its orbit from the sun and dragged out beyond the orbit of Neptune, not enough to be caught by Gleise, but enough to be lost to Sol.
If we are more 'advanced' than Dinosaurs - then surely we can live for longer than they did. 1.2 million years is not going to cut it.

The gravitational effect would be similar to the Gravitational effect Sol would have on Gleise when it passes inside the Oort Cloud barrier. It will be our planet's and its planets that will suffer most. The Asteroid Belt and Kuiper Belts would spray their Ex-Planetary remains around like a grenade of nails going off in all directions.

Sydney = Venus
Melbourne = Mars
Brisbane = Jupiter
Hobart = pluto
Adelaide = Neptune
Darwin = Mercury
Canberra = Uranus

hmm? You seem a person of the same thought 'pattern' as I.

Strange, very strange. That's the second post you've made that would be something i would post.

Who are you?

I'm Paul Onions. You can call me Paul Onions.

Now, I forgot Perth.

Perth = a lump of rock in the kuiper belt.

Perth = Dullsville

So basically, going by the evolutionary time it has taken for us to be here today. 1.2 million years is like a blink of an eye.

In terms of human life, I have lived 39 years. It feels like an eternity. In an evolutionary timeline, you will find that 1.2 million years seems like an eternity.

I'm almost 60 and it's been like a spark of flint against steel, a flash in the pan. I'm sorry your life has been such a drag, get out more, move.

Edit: Or maybe don't, you'll feel like Methuselah when you get to my age if you reach it.

I think my point is that my life has been so long for someone 39 years old BECAUSE I have lived a full life.

That won't happen.
It will have no effect on Earth's orbit.
The worst that will happen is that it will send a lot of comets into the inner solar system

What we have here is evidence of the Gliese Star side-swiping our Solar System (inside the Oort Cloud) in 'just' 1.2 million years.

That's not much time, in the scheme of our planet's existence and life upon it.

So basically, going by the evolutionary time it has taken for us to be here today. 1.2 million years is like a blink of an eye.

Currently, Humanity looks as if it could only survive another thousand years. So another intelligent species has just 1.2million years to evolve 'before' all life and this planet is 'possibly' destroyed.

This clip shows amazing mapping technique of our Galaxy via the Satellite GAIA. The amount of 'Exo Planets' is astounding - thousands! Just outside our Solar System.

A bit slow until the 12min mark.

Never mind that. Try to get a plumber at Christmas.
