What is the radius of our sun?
about 435,000 miles
Size and Distance Our Sun is a medium-sized star with a radius of about 435,000 miles (700,000 kilometers).
What is the radius of the sun and planets?
The radius of the Sun is 0.7 million km, and the radius of Jupiter (the largest planet) is 0.07 million km, both too small to resolve on this image.

How many square kilometers is the sun?
Surface Area of the Planets and the Sun
| Rank | Name | Surface Area(square km) |
|---|---|---|
| 1 | Sun | 6.088 x 1012 |
| 2 | Jupiter | 6.21796 x 1010 |
| 3 | Saturn | 4.27 x 1010 |
| 4 | Uranus | 8.1156 x 109 |
How many meters is the sun?
The International Astronomical Union voted in August 2012 to change the definition of the astronomical unit to a plain old number: 149,597,870,700 meters. The measurement is based on the speed of light, a fixed distance that has nothing to do with the sun’s mass.
How do you find the distance to the sun?
4. If an object is orbiting the Sun with an orbital period of 15 years, what is its average distance from the Sun? a = (225)1/3 = 6.1 AU….There is a simplified version of this law: P2 = a3 where:
- The object must be orbiting the Sun.
- P = period of the orbit in years.
- a = average distance of the object from the Sun in AU.
What is the length of the sun?
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).
Who measured the distance to the sun?
astronomer Aristarchus
Historically, the first person to measure the distance to the sun was the Greek astronomer Aristarchus around the year 250 B.C. He used the phases of the moon to measure the sizes and distances of the sun and moon.
How far are we from the sun right now?
The distance of The Sun from Earth is currently 147,256,766 kilometers, equivalent to 0.984351 Astronomical Units.
How do you find orbital radius?
Kepler’s Third law can be used to determine the orbital radius of the planet if the mass of the orbiting star is known (R3=T2−Mstar/Msun, the radius is in AU and the period is in earth years).
How is the size of the sun measured?
You can also measure the actual size of the sun with a ruler, tape measure and small mirror. Then measure the diameter of the projected image (d) and the distance between the wall in the mirror (l). These are in the same ratio as the actual diameter of the sun (D) to the true distance to the sun (L).
What is the radius of the Sun in kilometers?
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. Secondly, what is the radius of a circle?
What are the dimensions of the Sun?
The Sun’s Radius is… 695359 Kilometers. And the Diameter is …1390718 kms or 864337 Miles. This Radius of the Sun is almost 109 times larger than that of the Earth. The r of the Earth is… 6378 Kilometres. In other words both the dimensions are 1 : 109 rarios. Little more about the Sun… Average distance from…
How many Earths could fit inside the Sun?
More than one million Earths could fit inside the Sun if it were hollow. The Sun has a radius of 696.340 km / 432.685 mi and a diameter of 1.39 million km / 864.000 mi. Earth, for comparison, has a radius of only 2.439 km / 1.516 mi, and a diameter of just 12.742 km / 7.917 mi.
What is the mass of the Sun in kilograms?
The mass of the sun is 1.989 x 10 30 kilograms, about 333,000 times the mass of the Earth. The sun contains 99.8 percent of the mass of the entire solar system, leading astronomers Imke de Pater and Jack J. Lissauer, authors of the textbook ” Planetary Sciences,” to refer to the solar system as “the sun plus some debris.
