.
What is the approximate distance around the Moon and how did you get this distance?
The equatorial circumference of the Moon is 10,916 km. And the circumference of the Moon in miles is
6,783 miles

What is the approximate distance of the Moon from Earth?
The average distance between the Earth and the Moon is
384 400 km (238 855 miles)
.
How big is the circumference of the Moon?
The Moon is a little over a quarter the size of the Earth, with a circumference of
10,917 kilometres around the equator
and a radius (the distance from the core of the Moon to the surface) of just 1,737 kilometres.
How do we measure the distance to the moon?
- First, change 0.56 degrees to radians.
- Input the numbers into the arc-length formula, Enter 0.00977 radians for the radian measure and 2,160 for the arc length: 2,160 = 0.00977 x r.
- Divide each side by 0.00977. The distance to the moon is.
What is Earth’s approximate size?
Using those measurements, the equatorial circumference of Earth is
about 24,901 miles (40,075 km)
. However, from pole to pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around.
How long would it take to get to Mars?
The trip to Mars will take
about seven months
and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft’s flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
How long does it take to get from Earth to moon?
It takes
about 3 days
for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon. The specific distance depends on the specific path chosen.

How far is to the Moon and back?
The moon is, on average, 238,855 miles away. So technically people are saying they love you
477,710 miles
(the distance to the moon and back). You think that’s a lot, but in terms of a car, it’s not really.
How cold is in the moon?
Since the sun no longer heats the surface, the moon’s surface
can drop to -232 Celsius (-387 F)
. These are the coldest temperatures in our solar system, which means the surface of the moon becomes colder than that of Pluto. The poles of the moon and the craters are the places that reach the most extreme temperatures.
How many hours does it take to get to the Moon?
On average it takes
around three days
for a manned spacecraft to get to the Moon. This is based on the nine manned missions to the Moon and the six which landed on it’s surface. The exact average time for all these missions was about three days and six hours.
Does the moon rotate?
The moon does rotate on its axis
. One rotation takes nearly as much time as one revolution around Earth. … Over time it has slowed down because of the effect of Earth’s gravity. Astronomers call this a “tidally locked” state because it will now remain at this speed.
Does it rain on the moon?
The moon has a very thin atmosphere so it cannot trap heat or insulate the surface. There is no wind there, no clouds,
no rain
, no snow and no storms, but there is “day and night” and there are extreme differences in temperatures depending on where the sun is shining.
Who first measured distance to moon?
The earliest accounts of attempts to measure the lunar distance using this technique were by
Greek astronomer and mathematician Aristarchus of Samos
in the 4th century BC and later by Hipparchus, whose calculations produced a result of 59–67 R
Earth
(376000–427000 km or 233000–265000 mi).
How is the distance to the moon most accurately measured?
Because the
speed of light
is a known quantity and the lasers travel at the speed of light, scientists can accurately determine how far away the Moon is from Earth.
How long would it take to walk around the Earth?
QUESTION: How long would it take for someone to walk around the world? ANSWER: It is close to 25,000 miles (circumference) around the Earth. The average walking speed for most people is about 3 miles per hour. So we’re looking at
8,300 hours
of walking.
How can we find the distance of the Moon by parallax method Class 11?
⇒θ1+θ2=θ is the parallax angle. Hence, the distance of the Moon from the Earth is calculated to be
bθ1+θ2
.
How fast is the Earth spinning?
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly
1,000 miles per hour
.
Who discovered radius of Earth?
The first person to determine the size of Earth was
Eratosthenes of Cyrene
, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations. Eratosthenes was born around 276 B.C., which is now Shahhat, Libya.
What happens if you spend 5 years in space?
Long-term exposure causes
multiple health problems
, one of the most significant being loss of bone and muscle mass. Over time these deconditioning effects can impair astronauts’ performance, increase their risk of injury, reduce their aerobic capacity, and slow down their cardiovascular system.
Has anyone been lost in space?
A total of 18 people have lost their lives
either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. … The remaining four fatalities during spaceflight were all cosmonauts from the Soviet Union.
How long would it take to walk to Pluto?
At a minimum the distance between Earth and Pluto are 29 astronomical unit . An AU is defined as 149597870700 meters. If you are a halfway average walker, you will make about 6 kilometers an hour, which means it will take you 24932978,45 hours or
approximately 2844,28 years
to walk to Pluto.
What planet takes 7 years to get to?
Spacecraft Target Time | Messenger Mercury 6.5 years | Cassini Saturn 7 years | Voyager 1 & 2 Jupiter; Saturn; Uranus; Neptune 13,23 months; 3,4 years; 8.5 years; 12 years | New Horizons Pluto 9.5 years |

How old is Neil Armstrong?
Nearly 240,000 miles from Earth, Armstrong spoke these words to more than a billion people listening at home: “That’s one small step for man, one giant leap for mankind.” Armstrong died on August 25, 2012,
at age 82
.
How long was a day 5 billion years ago?
Sasaki said that the formation of the Earth and the Moon, 4.5 billion years ago, and the influence of the Moon on the planet are the determinants of the length variation of a day and a month throughout the Earth’s history. A day has not always been 24 hours long. In fact, it began lasting only
4 hours
.
Why did it take 3 days to reach the Moon?
The Moon’s gravity then pulled the spacecraft around the far side of the Moon where the CSM engine was burnt to brake the vehicle into Lunar orbit. Three days was simply how long it took to get from the
TLI engine burn to the CSM engine braking burn via the unpowered cruise
.
How much was Neil Armstrong paid to go to the moon?
Based on his salary and a 40-hour work week, that means he would have been paid roughly $33 for his time on the moon. Accounting for inflation, Armstrong was paid
$230 in 2019 dollars
— so it seems like NASA really got a bargain considering the giant, history-making risk Armstrong was taking.
What was the first life on Earth?
In July 2018, scientists reported that the earliest life on land may have been

Does the moon get hot?
Temperatures on
the moon are very hot in the daytime
, about 100 degrees C. At night, the lunar surface gets very cold, as cold as minus 173 degrees C. This wide variation is because Earth’s moon has no atmosphere to hold in heat at night or prevent the surface from getting so hot during the day.
