How Sun's Lost Twin Is Still Affecting The Solar System

In the 1980s, astronomers proposed that the Sun actually had an evil trouble-making twin called Nemesis that swings past the solar system every 26-27 million years. Its gravitational turbulence sends a cloud of comets hurtling our way. And it's possible that the twin was the culprit that kicked an asteroid into Earth's orbit, which eventually collided with our planet, triggering the fifth mass extinction event that wiped out the dinosaurs.

But the question is that if Nemesis is out there, where do we search for it?

Since most exosystems have planets several times Jupiter's size and our sun is a yellow dwarf, the primorial cloud was probably pretty light, so the most logical type of twin for our sun would likely be a brown dwarf.

When I first heard about Nemesis back in the 1990s I was breaking up with a girlfriend. She kept coming around every couple of weeks to get random things she "left" at my house and to stir up shit. I named her Nemisis.

[GururajBN]

Isn't this rather speculative? If Nemisis were indeed 500 AU away initially, how could it have moved by 600 LY? What could have propelled it away from its twin, our Sun? Isn't it more likely that the twin or the smaller sibling would have merged into Sun?

If it wasn’t for the Sun’s evil twin we wouldn’t be here.

If we map the stars that are 26 -27 million light years away from us, we would see that Nemesis would have to pass through several thousands of other solar systems, before any "returning" star came our way. There would be obvious trails of destruction littered along the way. There is nothing in the fossil record about some clockwork events as described.

Yes, but does sun’s evil twin solves the problem of why astroids always aim to land in craters

If that red dwarf is only 1.5LY distant, then it's currently in our sun's gravity well.

Nice fiction story, but it makes no sense.
This HD 186302 star, is supposedly 184 light years away, but formed just 500 AU away?. I mean if basically any star was 184 LY's away, it would have no effect on our solar system at all. And this small star, should then be able to disrupt the Keiper belt every 27 million years? That would require HD 186302 to be in an orbit, than comes into quite close contact with our solar system, maybe a few light years, which is bollocks. And on top of that, if it formed 500 AU away and is still gravitationally bound in some sense, to come within a few LY's, how come its now 184 light years away?
I mean come on now.

Our Sun and Nemesis or other trouble twin is a really interesting proposition and deserves astrometic data research new knowledge for me after 62 plus yrs.

There are old stories of the purple sun being the original sun. Old civilizations speak of Saturn being the original sun, then being replaced by the current sun after it died and faded.

I just feel like Jupiter was going to become the Sun's twin as it was especially closer to the Sun back in it's infancy phase, but just didn't. And over the years was gradually pushed away and moved to it's current location.

This spaceship you know as the solar system, with a engine called the Sun, endured more episodes than any bibical, sci-fi show. drifting into natural vessels. Earth has been through inconceivable infinite reincarnation form, size, celestial parts and civilizations ago.

Should've called it 'Nus'

Most star systems are Binary. Absolutely fascinating ☀️ Jupiter could be the Star that didn’t ignite. The Universe is full of mystery! Where would our Sun’s twin be? Astrophysics always is intriguing!

Interesting topic and well done video. Subscribed!

Is it possible that sun's twin is also orbiting in the milkyway galaxy and only crosses paths with the sun every 230 million years, which is approximately the time it takes the sun to orbit the milky way galaxy?

Sirius can be the Suns twin. Before 500 AD all ancient civilisations named Sirius the red star. Now it is blue. According to the Doppler effect, this means when it was red, it moved away from us. Now when it is blue, it comes back to his twin the Sun. Just heard this thought and find it very interesting.

Trace Sun's magnetic field on both sides and you will find out where is Nemesis. Thanks.

it should be our nearest sun system that is only 4 1/2 light years near to us and contains a G-class yellow-white this is the same type of star just like our own.... we are related to the Centauri constellation.... is is estimated that the G-class yellow-white type stars make up about only 15% of all our stars in our own Galaxy.... also the G-class star is a Heavy metals producer .... this is where Gold comes from....
