∙ 8y agoBarnard'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.

Which has a linear size or radius closest to the radius of a neutron star?
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
If a neutron star has a radius of 10 km and rotates 642 times a second what is the speed of the surface at the neutron star's equator in terms of the speed of light?
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
What is the relationship between raidus and area?
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 fourth closest star to earth. First is our Sun. Next is Proxima Centauri. Then comes Alpha Centauri. Which star is next?
Barnards Star, approximately 6 light years distant.
How hot is Barnards Star?
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).
In what unit do I measure the radius of a star?
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."
