What is the radius of the Sun’s solar sphere?

- Typically, the solar radius is defined as the distance between two points in the Sun’s photosphere where the optical depth is equal to two-thirds [citation needed]: 1 R = 6.957 x 10 5 km x displaystyle 1
- 1 R = 6.957 x 10 5 km x displaystyle 1
- 1 R = 6.957 x 10 5 km

## What is its mean radius from the sun as compared to Earth?

The radius of the sun, at 696,000 kilometers, is 109 times the radius of the Earth. It has a surface gravity of 274 m/s2, which is 28.0 times more than the Earth’s. It has a mean density of 1410 kg/m3, which is 0.255 times more than the mean density of the Earth. The diameter of the Sun, which is 1,392,000 km, is 109 times the equatorial diameter of the Earth, which is 12,756 km.

## What is radius of the sun?

As of right now, the Sun’s distance from the Earth is 147,418,141 kilometers, which is comparable to 0.985429 Astronomical Units (AU). When light travels from the Sun to us, it takes 8 minutes and 11.7340 seconds to arrive. The distance between the Sun and the Earth as a function of time is seen in the chart below.

## What is Earth’s radius in km?

As a result of data collected by 183 high-school students participating in a World Year of Physics project called “Measure the Earth with Shadows,” the radius of the Earth has been determined to be 6563 km, which is more than the previously accepted number of 6371 km.

## Can humans reach the Sun?

We might be able to, in theory. We don’t have the technology to safely transport astronauts to and from the solar yet, though, because the journey is so lengthy (the sun is 93 million miles distant, or around 150 million kilometers away). The surface of the sun has a temperature of around 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius).

## Is Earth moving closer to the Sun?

However, scientists have discovered that the distance between the sun and the Earth is shifting. This does not imply that we are moving closer to the sun. As the sun’s mass diminishes, its gravity weakens, causing the Earth to gradually recede away from it. Microscopically little movements are being made away from the sun (about 15 cm each year).

## What is the diameter and the radius of the sun?

The sun is almost a perfect spherical in shape. The distance between its equatorial diameter and its polar diameter is only 6.2 miles (10 km). The average radius of the sun is 432,450 miles (696,000 kilometers), which corresponds to a diameter of around 864,938 miles (132,000 kilometers) (1.392 million km). You might arrange 109 Earths in a straight line over the face of the sun.
