Epsilon Eridani: 2 planets? and 2 asteroid belts

Let us go on a journey to one of our near galactic neighbours, that of Epsilon Eridani. This is a relatively young star system only about 400 to 800 million years old, and has plenty of interesting things to explore. Let’s find out more.
At the right time of year look at the night sky and find Orion the Hunter, here it is. Now just look to the side. This is the constellation Eridanus, and this speck here, visible with the naked eye is Epsilon Eridani. Let’s get aboard our space and time machine for the short journey, just 10.48 light years.
Epsilon Eridani is a K type orange star with a diameter 74% and 82% of the mass of our sun. It has just over a third of the luminosity of the sun and a surface temperature of 5000 Kelvin, about 700 degrees cooler than our star.

Remember Reach ✊

Yeah 😎🤘

XD true

[@gogoscorner1111]

I have soul ties to Epsilon Eridania and this was the most amazing video ever! 😊

[@ReflectiveLayerFilm]

Awesome video. I like the way you modeled the asteroids and the breakup during collision.

[@LearningCurveScience]

Thanks very much. I quite enjoyed doing the simulations. I was only a bit happy with the collision. The large asteroid should have kept moving, but it took ages rendering so I wasn't doing it again. Thank you very much for watching the video.

Where is reach?

Remember reach ;v

a couple vids and subbed - can't get enough science since childhood.

[@markdavid7013]

K type stars may be a better bet for long term evolution of life than our Sun. It will last 3-4 times longer than Sol.

[@Strater117]

reach is somewhere in there (if u know u know)

I loved Starquake! As well as Dragon’s Egg, some of the most incredible mind expanding sci fi i've read. I don’t recall this star specifically tho, but i was more interested in other things at the time. I’ll have to look it up. Neutron stars are amazing. Have you read them? It’s so interesting reading Sci Fi from the 80s especially from people with real scientific backgrounds because you get a look into the past of science and all the progressions we’ve made, as well as what our old ideas about how stuff worked were. Some of them were pretty fantastical, and i love that. In those books a minor plot point is the presence of several small primordial black holes in the core of our sun, which is just so cool.

Love the music you choose to use for this video love Eridani I named my puppy Eridani

Epsilon Eridani c's existence is yet to be confirmed. Next time, you should do a video about the Kepler 10 system.

[@LearningCurveScience]

Yes absolutely, the existence of c is very much unconfirmed. I'm going to be making some genetics videos next, but I'll certainly look into Kepler 10. Thanks for the suggestion.

[@Barba72Simon]

@@LearningCurveScience There's a possibility an unseen 3rd planet might be in the Kepler 10 system, it's yet to be confirmed.

Epsilon-Eridani 2, aka REACH

[@JJO117]

Lol wanted to know more about this star system because of Halo but didn't expect a reference.

[@StephenGillie]

Earth's current extremely circular orbit, with eccentricity 0.017 as the video said, is a primary cause of global warming according to Milankovitch cycles. Distance from the sun is by far the primary driver of planetary temperature, and a more circular orbit keeps Earth heating evenly. When our orbit becomes more elliptical in like 10k years, we'll have orbital cooling periods again.

[@LuisAldamiz]

Looks like a nice tourist destination for dinosaur safaris... or amoeba safaris... or whatever.

[@desputnikcommander]

Nice video, only missing information was the orientation of the planetary disc

[@axure_9174]

my name is eridani haha

[@LearningCurveScience]

That's a cool name

[@doltBmB]

Are you going to cover Dagon, which just recently disappeared?

[@capscarlett7859]

Epsilon Eridani is where Babylon 5 is set. Orbiting the 3rd planet.
I bet there are smaller planets much closer to the star that we haven't found yet.

[@rursus8354]

4:09: Kepler's egg orbit theory was disproved by Kepler himself, with Tycho Brahe's position data for Mars, with which he proved that the orbits are instead ellipses.

This is said to be where the hostile insects are from

[@LearningCurveScience]

Oh blimey, I don't like the idea of hostile insects.

[@cwise.]

@@LearningCurveScience nor do I, but apparently we have allies. I find my information on the channel called earthfiles

[@Michael.Chapman]

They are the Trantaloids, according to the briefing Reagan received. If this system is so young I wonder how such an advanced technological species could have had time to evolve?

[@Encephalitisify]

So basically the system is going through a bombardment stage.
