Barnards star is a highly variable star and can have different brightnesses.

Barnard's Star also known as Barnard's "Runaway" Star [See Link] is a very low-mass red dwarf star approximately 6 light-years (5.98 ly) away from Earth in the constellation of Ophiuchus (the Snake-holder)
Barnard's Star is a very low-mass red dwarf star.
The estimated surface temperature of the red dwarf known as Barnard's Star is "only" about 3134 K, compared to our Sun's surface temperature of about 5778 K. It radiates mostly in the infrared, and is the closest detected red dwarf to Earth, about 6 light years away.
Barnard's Star is about 6.0 light years away from Earth.
Barnard's Star is just under 6 light-years from Earth (5.98 ly), so just under 6 years.
Barnards star is approximately 6 light years from us.
It has a diameter between 15% to 20% of that of the Sun, around 210,000 to 280,000 km.
It is huge i saw it
its about 70 billion
Br is the atom with the smallest. K+ is the ion with the smallest radius. In general, the shape with the smallest radius has the smallest diameter
The Radius of the Star is 10 KM. Now we need to find the diameter. Circumference equals pi times the Diameter. That is twice the Radius, which is 20. Now we need to get the Diameter. We multiply the diameter by pi. 20 times 3.1416. 20 * 3.1416 = 62.838. Now we multiply the circumference in kilometers by the speed. 62.832 * 642 = 40,338. Now we take the speed of light, 299,997 per second and divide it into the speed of a point on the equator of our star going 40,338 kilometers per second. 40338 / 299997 = 0.1345
The relationship between the radius and area of a circle is as follows: Area of circle = 3.14 x Radius x Radius or 22/7 x Radius x Radius
what is the similarities between the ulna and the radius
The radius of a circle is half the length of the diameter. Scroll down to related links to find more about the diameter and the radius.
It has a radius of between 0.15 and 0.20 that of our Sun. The Sun has a radius of about 696,000 km, so Barnard's Star has a radius of between 104,400 km and 139,200. Average about 121,800 km
Barnards star has a mass of between 0.15 and 0.17 solar masses.
Our Galaxy, the Milky Way Galaxy
Barnards star has a mass of between 0.15 and 0.17 solar masses.
Barnard's Star is approximately 6 light years away.
Barnard's Star is a very low-mass red dwarf star and has a spectral type of M4V.So it has the colour red.
Barnards Star, approximately 6 light years distant.
The name is "Barndard's star". Wikipedia lists it at 3,134 ± 102 Kelvin. (Subtract 273 degrees if you want this in Celsius.) The "plus or minus" refers to the uncertainty (estimated error).
You can use kilometers. Or you can compare it to the radius of our Sun, and say, for example, "This star has 600 times the diameter [or radius] of our Sun."
That's the approximate radius of a neutron star, a.k.a. a pulsar.
