# What Is The Scientific Notation For Earth?

For example the age of the Earth (see above) can be written as 4.6 X 109 years. This means that this number has 9 places after the decimal place – filled with zeros unless a number comes after the decimal when writing scientific notation. So 4.6 X 109 years represents 4600000000 years.

What is the circumference of the earth in scientific notation?

The circumference of the earth is approximately 40 075 km .

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.

### how far is the sun from the earth in scientific notation?

Earth is approximately 93,000,000 miles from the sun. Express this distance in miles in scientific notation.

What is the weight of the earth in scientific notation?

In scientific notation, Earth’s mass is 5.97×1024 kg. The 5.97 part is called the coefficient; the 24 is called the exponent.

### How do we measure the Earth?

On the day the Sun shone on the bottom of the wells in Syene, Eratosthenes measured the Sun’s position in the sky over Alexandria. It was seven degrees away from the zenith, meaning Syene must be seven degrees away from Alexandria as measured on the circle that is Earth’s circumference.

### How many feet is the world?

The site below gives the circumference of the Earth at the equator as 24,901.55 miles. As there are 5,280 feet in a mile, this equates to 131,480,184 feet.

oblate spheroid

### What is the mean of pi?

Definition: Pi is a number – approximately 3.142. It is the circumference of any circle divided by its diameter. The number Pi, denoted by the Greek letter π – pronounced ‘pie’, is one of the most common constants in all of mathematics. It is the circumference of any circle, divided by its diameter.

6,371 km

### What is the shape and size of the Earth?

Earth’s circumference and diameter differ because its shape is classified as an oblate spheroid or ellipsoid, instead of a true sphere. This means that instead of being of equal circumference in all areas, the poles are squished, resulting in a bulge at the equator, and thus a larger circumference and diameter there.

3,959 miles

### How much does the moon mass?

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).

### How is scientific notation used in astronomy?

The Scientific Method This is one reason astronomers and other scientists use scientific notation when working with very large or very small numbers. Scientific notation is a system for writing and working with numbers that makes it much easier to deal with numbers that are very small or very large.

### How far is the moon from the sun?

The Moon, on average, is about 150 million kilometers away from the Sun. That’s actually an interesting coincidence, since the Earth orbits about 150 million kilometers away from the Sun.
