Constellations are a human invention, but yes, the Sun would appear in the night sky just like any other star as seen from an exoplanet, provided it's close enough to be seen with the naked eye.

From a planet orbiting one of the stars of Alpha Centauri, the Sun is close to the bright stars of Cassiopeia. From Barnard's Star, the Sun aligns nicely with the belt of Orion.

Here are a few more, including charts! https://skyandtelescope.org/astronomy-blogs/explore-night-bob-king/see-the-sun-from-other-stars/

How far away would it visible - assuming a planet has an atmosphere like earth and whatever alien had similar vision to humans?

Waddensky t1_j6eevak wrote

The Sun has an absolute magnitude of 4.8. The (human) naked-eye limiting magnitude is 6.5. The Sun would be visible to the naked eye up to a distance of around 70 light-years.

Can we detect stars that are more than 70 light years away from us? Do telescopes make more stars visible from further away?

dumdodo t1_j6g04is wrote

The Orion Nebula, one of the "stars" in the constellation Orion, is 1400 light years away.

Different types of stars have different magnitudes, and can be visible at different distances, as do other objects, like nebulas.

And yes, with a telescope, you can see numerous additional stars. The Milky Way becomes a boring group of stars when viewed through a telescope, because they are no longer tightly packed.

Depends on the size of their pupil and sensitivity of their eye equivalent features.. if they have a telescope then 5 billion light years because that’s how old the sun is… if their pupils were massive I believe they could technically see it with the naked eye but it would be incredibly tiny.. they just need to capture enough light from the source to be visible

I remember reading somewhere that the sun is not even the brightest star in the sky when you get out to the oort cloud, but certainly it would be visible, but we tend to make constellations with bright stars, so probably not very far off. A quick google, maybe about 60 lightyears or so and it would be barely visible, but 0-40’s it might be in a constellation.

redstercoolpanda t1_j6dlhzt wrote

but how would that be possible? considering it would be by far the closest. is it just a case of bigger stars making more light even if there farther away?

12

VertigoOne1 t1_j6dtgn8 wrote

Because our sun is a dwarf star, it is actually very puny. The only reason it is so bright is because it is so close, Sirius is 9 lightyears away and is 25 times more luminous, and absolute magnitude of 1.45, the sun is 4.85. Canopus is 300lj away, is the second brightest star in the sky. Our sun is very lightweight. If you put canopus at the distance of Sirius it would be brighter than the moon.

citybadger t1_j6ebeq3 wrote

The Sun is below the average but above the median brightness, because so many stars are red dwarfs.

The population is stars is like rocks on a beach. Most are grains of sand. Then there are pebbles of various sizes. And then there are a few rocks and even giant boulders.

cantwejustbefiends t1_j6fgd41 wrote

This is more a testament to how large the Oort Cloud is since the sun is pretty average. Sirius is 25x the brightness of our sun, but the edge of the Oort Cloud is 200,000x farther from the sun than Earth is (Pluto and the Kaiper Belt are only 40x and 50x). If Earth was at the edge of the cloud, Sirius would be only 3x farther then the sun; so at 25x brighter it would be brighter. But within a 20 ly distance our sun is one of the brightest, and of the 130 closest stars our sun is actually the 7th brightest.

The Oort Cloud reaches out 3 ly, and for comparison our closest neighboring system, Alpha Centauri, is 4.3 ly. If you were at the edge of the Oort Cloud, our sun would be the 5th closest star to you.

I don’t know if it still exists or not, but there was old open-source planetarium software, called Celestia I believe, that let you play around with this. For example, on a planet around Alpha Centauri, the Sun would appear as a sixth bright star in Cassiopeia, making the “W” look more like a zig-zag.

internetboyfriend666 t1_j6cxd8o wrote

It's certainly possible. Our sun would be visible to the (human) naked eye out to at least a few dozen light years, so depending on how those alien's eyes worked, they could potentially see our sun as part of a constellation.

uranusisenormous t1_j6d1gfb wrote

Good way of putting it. The sun is def visible to other planets. But a constellation is an abstract concept that almost certainly requires some kind of intelligence. I don’t think dogs look at the stars and see archers or lions or bears. And even if they did, they’d have no language to pass that info down through the generations.

I remember once reading that, viewed from Alpha Centauri, we would be a little extra “zag” at the bottom end of Cassiopeia.

Kinda puts things into perspective.

ferrel_hadley t1_j6d2dxq wrote

The Sun is about brighter than a full Moon from Pluto. But hypothetically our Sun would appear as a super bright star from within the Solar System. Comets and the other planets would not be visible to human eyes. Though its slow 248 year movement across the sky would make it not fit in as a constellation.

But as you push deeper out while still part of the solar system that movement would become less and less obvious.

This is theoretical and does not answer your question directly but from a theoretical planet in the outer solarsystem then yes the Sun would be part of constellation to any civilisation only lasting a couple of hundred years.

Are you saying that the light we see on Earth on a full moon night is the approximate amount of light we would see coming from our sun if we were to stand on Pluto?

yes, afaik its about 1000x less bright than daylight. our eyes have a pretty good low and high end range. you won't see much color probably.

Sun is small and would be pretty faint from just a few light years away, but it’s possible.

Depending on the view point from another distant world, the Sun would either be in the constellation Capricornus or if it's from an Alpha Centauri world, Cassiopeia's outcast regions.

Our sun IS factually part of a constellation, the real question is, is it part of one, named by aliens.

coleisman t1_j6erqqz wrote

not likely to be. our star isn’t particularly bright as stars go, most of the stars in our constellations are tens to thousands of times more luminous than our sun.

even if visible it wouldn’t stand out at all and wouldn’t likely be in a constellation unless they were at alpha centauri.

MikeLinPA t1_j6fh1qt wrote

Really, any small group of bright enough stars can be imagined into constellations. The little dipper could be seen as the toilet of the gods in someone's mind. This means that Sol could very well be part of the septic system constellation from some other point of view.

Niven42 t1_j6gb84p wrote

The Sun's absolute magnitude (how bright it would appear at a distance of 10 parsecs), is about +4.83, which means that out to around 30 light years, it appears as a fifth magnitude star or brighter. Although there are many factors to how bright stars appear while observing from Earth, the classic constellations were limited to around fifth magnitude, or brighter (magnitude is an inverse scale; smaller numbers are brighter). So, for at least all systems out to around 10-12 parsecs, the Sun is bright enough to be included in their constellations (if they used the same criteria as our ancients did when creating star groupings).

Here is a chart of around 130 star systems where the Sun would be likely to appear as a significant constellation star.

BOBauthor t1_j6grjgn wrote

If observers in the alpha Centauri system looked at our Sun, they would see a star of apparent magnitude 0.5, which is very bright. The Sun would be in the constellation Cassiopeia, and could be considered as an extension of it. (Cassiopeia itself wouldn't appear much different.) Here's a Sky & Telescope article about this.

Plus, the sun rotates on its axis about once a month (the actual rotation rate varies depending on the latitude, which is possible because the sun isn’t rigid), so we get a regular look at every part of its surface.

smilingpike31 OP t1_j6gy6n0 wrote

Wait does it even matter if the sun is on an axis? Well it does create an energy source for every direction so does it matter for it to have an axis?

1

Norwester77 t1_j6h0fq6 wrote

It does radiate energy in all directions, but the material in the sun is rotating, so it necessarily has an axis of rotation. The rotation has other effects, like twisting the sun’s magnetic field into a spiral.
