they would appear bright enough to be seen, although too bright to look at
Deneb is a bright star located in the constellation Cygnus, also known as the Northern Cross. It is approximately 1,425 light-years away from Earth and is one of the farthest naked-eye stars visible to us. Deneb is part of the Summer Triangle asterism, along with Vega and Altair.
If Deneb and Rigel were placed at Alpha Centauri's distance from Earth (about 4.37 light-years away), they would appear as extremely bright stars in the sky, similar to our Sun. Deneb, a distant supergiant star, would still shine brightly but not as brightly as the Sun. Rigel, a blue supergiant, would appear much brighter than Deneb due to its larger size and luminosity.
No, Rigel is actually larger than Deneb. Rigel is a blue supergiant star located in the Orion constellation, while Deneb is a blue-white supergiant star located in the Cygnus constellation.
This is the order from smallest stars to the biggest stars: Alpha Centauri, Procyon, Vega, Pollux, Polaris, and Deneb. These are the size(diameter) of them; though the size of the stars are not 100% accurate so they are likely to be predicted. Alpha Centauri is 1,527,000 Procyon is 2,652,000 Vega is 3,827,000 Pollux is 11,617,000 Polaris is 44,217,000 and Deneb is 203,000,000
One of the brightest stars in Cygnus is Deneb. It is a white supergiant and one of the vertices of the Summer Triangle asterism. Deneb is located approximately 2,600 light years away from Earth.
The Star Deneb is around 1400 light years from our solar system.
Adding to what Hilmas Zonneveld posted, Cetus is another constellation where Alpha (Menkar) is not the brightest star. Menacer is mag 2.4. The brightest is Beta Ceti, Deneb Kaitos or Diphda. Several stars are known as Deneb or have that word in their names. Deneb means 'tail'.
The brightest star in the constellation Cygnus is Deneb. It is a supergiant star located around 1,425 light-years away from Earth. Deneb is one of the brightest stars in the night sky and is part of the Northern Cross asterism in Cygnus.
