What is the distance between Earth and moon today?

The Moon is an average of 238,855 miles (384,400 km) away.

How do you calculate Earth’s distance to the moon?

Remember how a 1-inch diameter sphere perfectly blocks the Earth at about 108 inches away from the eye? Finally, they multiplied 108 by 2300 miles to approximate the moon’s distance is about 248,000 miles away.

What is a light year in scientific notation 9460000000000 km?

A light year is the distance that light can travel in one year. 1 light year = 9,460,000,000,000 km. One light year in scientific notation is expressed as 9.46 × 10¹² km.

What is 0.000000456 in scientific notation?

Similarly, starting with 0.000000456, move the decimal point seven places to the right yielding 4.56, and multiply by 10−7, to give the result4.56×10−7.

What object is 386000 km from Earth?

The distance between the Earth and the moon is 386000 km.

What is Earth’s moon’s real name?

Earth’s only natural satellite is simply called “the Moon” because people didn’t know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610. In Latin, the Moon is called Luna, which is the main adjective for all things Moon-related: lunar.

Which planet is 778600000 km from the Sun?

Name: Jupiter Distance from the Sun: The distance from the Sun to Jupiter is 778,600,000 Km! Length of day: The days on Jupiter only last 9.9 hours. Length of year: The years on Jupiter last 11.9 Earth years, that’s crazy! Number of moons: Jupiter has 79 moons, more than any other planet in our Solar system.

What is km in scientific notation?

Scientific Notation

Prefix	Unit Abbreviation	Example
mega	M	1 megameter (Mm)=106m
kilo	k	1 kilometer (km)=1,000m
hecto	h	1 hectometer (hm)=100m
deka	da	1 dekameter (dam)=10m

How do you write distance in scientific notation?

In scientific notation, the distance is written as 1.5 × 1011 m. The coefficient is the 1.5 and must be a number greater than or equal to 1 and less than 10. The power of 10, or exponent, is 11 because you would have to multiply 1.5 by 1011 to get the correct number.

What is the distance between Earth and moon in physics?

Complete step-by-step answer: The answer is option B , the exact distance between earth to the moon is 384,400 km.

When moon is nearest to the Earth?

Fast Facts. A supermoon occurs when the Moon’s orbit is closest (perigee) to Earth at the same time the Moon is full.

How long is 1 year on the moon?

Since each lunation is approximately 291⁄2 days, it is common for the months of a lunar calendar to alternate between 29 and 30 days. Since the period of 12 such lunations, a lunar year, is 354 days, 8 hours, 48 minutes, 34 seconds (354.36707 days), purely lunar calendars are 11 to 12 days shorter than the solar year.

What is the distance between Earth and space in KM?

Yet the edge of space – or the point where we consider spacecraft and astronauts to have entered space, known as the Von Karman Line – is only 62 miles (100 kilometers) above sea level.

How many km from Earth is space?

A common definition of space is known as the Kármán Line, an imaginary boundary 100 kilometers (62 miles) above mean sea level. In theory, once this 100 km line is crossed, the atmosphere becomes too thin to provide enough lift for conventional aircraft to maintain flight.

Why does it take 3 days to get to the Moon?

Historically, most lunar missions have taken about three days to reach the moon, assuming the moon is at an ideal distance of 240,000 miles (386,243 kilometers) away. This means astronauts travel roughly 3,333 mph (5,364 kph) on their journey to the moon.

How long is 1 year on the Moon?
