# What is the circumference of the sun?

The sun is approximately 4,366,813 kilometers (2,713,406 miles)
in circumference.

The circumference of the Sun is approximately 4,366,800 km

### What do you if you divide the circumference of the sun by its diameter?

If you divide the circumference of the sun by its diameter you will have found the number called "Pi". The actual number is an infinite string of digits that starts 3.14159. This is true for any circle of any size: The circumference divided by the diameter equals Pi. Conversely if you know the diameter you can multiply that by Pi (3.14159) and that will give you the circumference. The diameter multiplied by Pi equals the…

### What is the perimeter of the sun?

The perimeter of the sun would be calculated as the perimeter (circumference) of a circle which is derived by multiplying 'pi' (3.14) by the diameter. The Sun's diameter is 1.4 million kilometers. Therefore, the circumference of the sun is 3.14 multiplied by 1.4 million which is equal to 4.396 million km.

### How big is the earth and how big is the sun?

The Earth has a diameter of 8825.25(12756.28 km) and a circumference of about 25000 miles (40000 km). The Sun has a diameter of about 865000 miles (1391780km) and an equatorial circumference of about 2.7 million miles (4.4 milion km). The Sun is 109 times wider than the Earth and about 1.3 million Earths could fit inside the Sun.

### How is the orbital circumference of a planet determined?

The orbital circumference of a planet is determined by both the mass and size of a planet. Although a planet will orbit the sum in an eliptical sphere shaped orbit, the circumference of these are almost always relative to the mass and density of the planet. It is also determined on how far away it is from the sun. The orbital circumference of a planet is determined by both the mass and size of a…

### How many miles around is the sun?

The Sun is fairly round, so you can apply the formula for a sphere. The circumference is simply the diameter multiplied by pi. The radius of the sun is estimated to be about 432,450 miles, so the diameter is about 864,900 miles. That suggests a circumference of about 2,717,161 miles (2.7 million miles). But since the sun is a ball of gas, there is no definite solid surface to measure. Astronomers have to use an…

### How did Eratosthenes discover the approximate circumference of the earth?

He used only simple geometry and observation of the sun Eratosthenes assumed that the sun was so far from the earth that its rays were practically parallel when they reached it, and that the earth was spherical. Then, he calculated the the degree of elevation of the sun at Alexandria and Syene at specific times, and estimated the distance between the two. By so doing, he was able to calculate what he thought was the…

### How long would a day be if you were closer to the sun?

Distance to the sun does not regulate the length of a day, it's actually the circumference of the orbiting body. Since one full revolution is one day and one night, the larger the circumference the longer the day would be; the converse also holds true. The orbit determines the length of the year. Mercury, the closest planet to the sun, has the shortest year since it has the shortest orbit (path around the sun), while…

### How many killiometers those the earth travel the sun?

The distance from Sun to Earth is about 150 million kilometers; Earth's orbit is (approximately) circular, so just use the formula for the circumference of a circle (= 2 x pi x radius), using 150 million kilometers for the radius. The distance from Sun to Earth is about 150 million kilometers; Earth's orbit is (approximately) circular, so just use the formula for the circumference of a circle (= 2 x pi x radius), using 150…

### What is the impact of Hellenistic culture on modern society?

From Hellenistic culture we get theories on astronomy, mathematics, and physics. Aristarchus's theories include, that the sun was 300 times larger than the earth, but he grossly underestimated it, and the earth and other planets revolve around the sun. Eratosthenes estimated earths circumference to be 28,000-29,000 miles long, close to the actual circumference. From Hellenistic culture we get the Pythagorean theorem and pi (the ratio of a circumference of a circle to its diameter) Archimedes…
