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.

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

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

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

[JessicaRodriguez]

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

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.

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

[Strater]

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

[doltBmB]

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

[AshiqSa]

❤😢Please upload more videos like this❤

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.

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

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.

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

[rursus]

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.

Does anyone know the song at the beginning of the video?

[genxlife]

Epsilon Eridani: Future location of the Earth Alliance space station Babylon 5! (lol!)

[capscarlett]

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.

[cwise.]

This is said to be where the hostile insects are from

[EDF_Fencer]

Epsilon eridani isn't that the planet reach from halo
