Answer 2

It depends on how you measure. The sun puts out solar wind, which travels into the interstellar medium. At some point, it is slowed down to an effective stop. This is known as the heliopause. BUT, it is not spherical. The closest edge is approximately

100 AU = 1.49598e10 km = 0.00158128588 lightyears

away from the sun. Pluto's farthest distance from the sun is

49 Au = 7.330302e9 km

so that can be considered a radius as well.

It all depends on your definition. Be sure to say what measure you are using.

Answer 3

F=GMm/R2

Where F is the force between the sun and the earth.
G is the Gravitational constant
M is the mass of the Sun
m is the mass of the Earth
R is the distance between the Sun and Earth

a=GM/R2

a is the gravitational acceleration due to the mass of the Sun at the Earth's orbital radius.

a=v2/R

v is the angular velocity of the Earth as it orbits the Sun.

v=2PiR/P

Pi is the constant Pi 3.14159....
P is the period of the Earths orbit 365.25 days

v2 =4(Pi)2R2/P2

a=4(Pi)2R/P2

GM/R2 =4(Pi)2R/P2

M=4(Pi)2R3/P2

Knowing the value of Pi, R, G and P then we can calculate the Mass of the Sun.

Answer 4

The Wikipedia lists its diameter as 1.392684×106 km, so the radius would be half this amount. About 700,000 km, or 700 million meters.

That's the equatorial diameter; the diameter from pole to pole is not much less.

Since the diameter of the sun is 100 times that of earth, that means the radius is about 50 earth diameters.

Answer 5

That's a constantly changing distance which, during the

course of one year, averages about 93 million miles.

Answer 6

The planet Mercury is the smallest of the 8 major planets and the closest to the Sun. It has a radius of 2439.7 km (about 1516 miles).

Answer 7

The radius of the Sun is approximately 696,340 kilometers.

Answer 8
