How big is the earth in scientific notation?

Rate this Question and Answer
Asked By: Lena Frontelo | Last Updated: 18th May, 2020
We will use scientific notation all the time in this course. Size of Sun and other astronomical objects: Earth: radius = 6378 kilometer, diameter = 12756 kilometers. Sun: radius = 696,000 kilometers, > 100 times larger.

Similarly one may ask, what is the diameter of the 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.)

One may also ask, how big the earth is? 6,371 km

Furthermore, what is the distance in scientific notation?

That’s a lot of zeros, and it is easy to lose count when trying to figure out the place value of the number. Using scientific notation, the distance is 5.88×1012 5.88 × 10 12 miles. The exponent of 12 tells us how many places to count to the left of the decimal.

What is the real shape of the earth?


What is the radius of Sun?

696,340 km

What is Earth made of?

The Earth is made out of many things. Deep inside Earth, near its center, lies Earth’s core which is mostly made up of nickel and iron. Above the core is Earth’s mantle, which is made up of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals.

What is Earth’s Planet number?

Earth. The third planet from the sun, Earth is a waterworld, with two-thirds of the planet covered by ocean.

How much is a trillion in scientific notation?

Names for large numbers
Scientific notation American name (Short Form) British name (Long Form)
105 Hundred thousand Hundred thousand
106 Million Million
109 Billion Thousand million
1012 Trillion Billion

What is the exact radius of the earth?

The radius of Earth at the equator is 3,963 miles (6,378 kilometers), according to NASA’s Goddard Space Flight Center. However, Earth is not quite a sphere. The planet’s rotation causes it to bulge at the equator. Earth’s polar radius is 3,950 miles (6,356 km) — a difference of 13 miles (22 km).

Who discovered radius of Earth?


What is the exact mass of the moon?

The moon’s mass is 7.35 x 1022 kg, about 1.2 percent of Earth’s mass. Put another way, Earth weighs 81 times more than the moon. The moon’s density is 3.34 grams per cubic centimeter (3.34 g/cm3).

What is scientific notation in math?

CCSS Math: 8.EE.A.3. Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

How do you do scientific notation?

To write a number in scientific notation:

Put the decimal after the first digit and drop the zeroes. To find the exponent count the number of places from the decimal to the end of the number.

How do engineers use scientific notation?

The habit in engineering is to use a slightly modified scientific notation. Engineers like exponents in multiples of three. This means the digits to the left of the decimal point fall in the range of one to 999. Our minds do a pretty good job relating to numbers in this range.

When writing a number in scientific notation how many digits should be to the left of the decimal?

The first “interesting” digit in this number is the leading 9, so that’s where the decimal point will need to go. To get from where it is to right after the 9, the decimal point will need to move seven places to the left.

How far away is the sun in scientific notation?

Scientific Notation: It is very inconvenient to always have to write out the age of the universe as 15,000,000,000 years or the distance to the Sun as 149,600,000,000 meters.

Who named Planet Earth?

The answer is, we don’t know. The name “Earth” is derived from both English and German words, ‘eor(th)e/ertha’ and ‘erde’, respectively, which mean ground. But, the handle’s creator is unknown. One interesting fact about its name: Earth is the only planet that wasn’t named after a Greek or Roman god or goddess.

What does outer space look like?

Space is full of light, but it doesn’t look like it. The color black usually signals the absence of light. But inside the solar system, space is filled with light.

What does Earth look like from space?

From space, Earth looks like a blue marble with white swirls. Some parts are brown, yellow, green and white. The blue part is water. Water covers most of Earth.

How much water is there in the world?

How much water is that? It’s roughly 326 million cubic miles (1.332 billion cubic kilometers), according to a recent study from the U.S. Geological Survey. Some 72 percent of Earth is covered in water, but 97 percent of that is salty ocean water and not suitable for drinking.

How do you describe Earth?

Earth is really an “oblate spheroid,” because its spin causes it to be squashed at its poles and swollen at the equator. Water covers roughly 71 percent of Earth’s surface, and most of that is in the oceans. About a fifth of Earth’s atmosphere consists of oxygen, produced by plants.
