What is the diameter of the sun answer?

Radius, diameter & circumference The mean radius of the sun is 432,450 miles (696,000 kilometers), which makes its diameter about 864,938 miles (1.392 million km). You could line up 109 Earths across the face of the sun. The sun’s circumference is about 2,713,406 miles (4,366,813 km).

What is the diameter of the sun in scientific notation?

~Sun. The Sun is the largest star located at the center of the Solar System. It has a diameter of 1,390,000 km (Scientific notation: 3.19 x 10e6 km) and a radius of 56,378.15 km (Scientific notation: 5.6378 x 10e4 km) The sun gives off energy as electromagnetic radiation.

What is the size of Earth in scientific notation?

Earth is the third planet from the sun. 71% of Earths surface is water. Its the only planet with life. It has a diameter of 12,756.3 km (Scientific notation: 1.2756 x 10e4) and a radius of 56,378.15 km (Scientific notation: 5.6378 x 10e4 km.)

Is the sun getting bigger?

Because the Sun continues to ‘burn’ hydrogen into helium in its core, the core slowly collapses and heats up, causing the outer layers of the Sun to grow larger. It is a very gradual process, and in the last 4 billion years, the Sun has barely grown by perhaps 20 percent at most.

What holds the sun in place?

The sun’s gravitational force is very strong. The sun’s gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun’s gravitational pull, all the planets in our solar system orbit around it.

Which has the largest diameter?

Largest Planet: Jupiter The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume. Jupiter’s mass is more than 300 times that of Earth, and its diameter, at 140,000 km, is about 11 times Earth’s diameter.

How do you calculate the size of the Sun?

You can now use your value for the angular size of the Sun to calculate the physical size of the Sun. Your number for angular size converted into radians × distance from Earth to the Sun = size of the Sun

How is the diameter of the sun related to the distance to the Earth?

The ratio of the diameter of the sun to the distance to the earth is proportional to the ration of the diameter of an image of the sun to the distance between the image of the sun produced by a pinhole and the cardboard the image is reflected upon. A is the diameter of the sun (km).

How to measure the diameter of the Sun in eighth grade?

Students will use an index card with a hole punched in it to project an image of the Sun on their paper.

How big is the center of the Sun?

Model values at center of Sun: Central pressure: 2.477 x 10 11 bar Central temperature: 1.571 x 10 7 K Central density: 1.622 x 10 5 kg/m 3.
