That's the approximate radius of a neutron star, a.k.a. a pulsar.
The area of the circle is the largest part. The next largest would be the circumference. Then the diameter, then the radius
The radius of a star is a measure of its size, typically expressed in units such as solar radii, where one solar radius is the radius of the Sun, approximately 696,340 kilometers (about 432,690 miles). The radius can vary widely among different types of stars, ranging from less than a third of the Sun's radius for small red dwarfs to more than 1,000 times the Sun's radius for massive supergiants. The radius is determined through methods such as observing the star's brightness, temperature, and spectral characteristics.
The radius of the largest circle you can fit is 2.72cm
No, but the diameter of a circle is its largest chord
The largest known star "VY Canis Majoris" has a 987,600,000 km radius whereas the sun only has a puney 695,500 km radius.
NML Cygni or V1489 Cygni is a red hypergiant star and the largest star currently known, at about 1,650 times the Sun's radius
Saturn has the largest radius followed by Jupiter.The Equatorial radius of Saturn (not the rings) is about 60,268 kmThe Equatorial radius of Jupiter (not his rings) is about 71,492 kmso Jupiter is larger
The star R136a1 by mass and luminosity. The star VY Canis Majoris by radius and volume.
No, VY Canis Majoris is the largest star we know about, the radius of this star is 1,800-2,100 times that of the (our) Sun.
Jupiter is the largest planet and therefore has the largest radius. The radius of Jupiter is 43,441 miles (69,911 kilometers).
francium has the largest ionic radius
In terms of diameter 'VV Cephei A' probably holds this position.
The largest known star now is UY Scuti with a diameter 2,375,828,000 km. UY Scuti has the radius of 1,516-1,900 solar radii, with the median radius of 1,708 solar radii, or approximately 7.94 astronomical Units.
The largest radius among the options provided.
Francium has the largest atomic radius of all the elements on the Periodic Table.
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."
