How many km is the moon?

How far away is the Moon from the Earth? The average distance between the Earth and the Moon is 384 400 km (238 855 miles).

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 the journey from Earth to moon?

The approximately 250,000-mile journey from Earth to the moon took Apollo astronauts about three days.

How old is the Moon?

Scientists looked to the moon’s mineral composition to estimate that the moon is around 4.425 billion years old, or 85 million years younger than what previous studies had proven. That’s around the time Earth’s core settled, the researchers said.

Which country is the closest to the Moon?

Due to a bulge around the equator, Ecuador’s Mount Chimborazo is, in fact, closer to the moon and outer space than Mount Everest.

How long is a flight to Mars?

According to NASA (opens in new tab), a one-way trip to Mars would take about nine months. If you wanted to make it a round-trip, all in all, it would take about 21 months as you will need to wait about three months on Mars to make sure Earth and Mars are in a suitable location to make the trip back home.

How long is 1 day in moon?

The short answer is this: A day is the length of time between two noons or sunsets. That’s 24 hours on Earth, 708.7 hours (29.53 Earth days) on the Moon.

Why is it 13 minutes on the Moon?

Thirteen minutes is the time it took the gold-wrapped, four-legged Lunar Module to reach the moon surface after separation from the command module, which remained in orbit around the moon. The BBC podcast 13 minutes to the Moon tells the story of how incredible the moon landing was in fact.

How long is 1 hour in space?

Explanation: The clocks in space tick more slowly than clocks on Earth., HENCE COVERING LESS TIME AS COMPARED TO EARTH IN THE SAME DURATION. One hour on Earth is 0.0026 seconds in space. Thus, upon calculation we find that one hour on Earth is equivalent to seven years in space.

How far is space from Earth?

The U.S. military and NASA define space differently. According to them, space starts 12 miles below the KaÌ rmaÌ n Line, at 50 miles above Earth’s surface. Pilots, mission specialists and civilians who cross this boundary are officially deemed astronauts.

Can we travel to the Moon?

NASA plans to launch an uncrewed spacecraft, part of the Artemis I mission, as soon as this weekend to orbit the moon and then return to Earth after about a month and a half. If everything goes as planned, a future mission could land astronauts on the moon in 2025.

How long will the moon live?

Calculations of the evolution of the Earth/Moon system tell us that with this rate of separation that in about 15 billion years the Moon will stop moving away from the Earth. Now, our Sun is expected to enter its Red Giant phase in about 6 to 7 billion years.

What is the oldest planet?

Jupiter formed less than 3 million years after the birth of the solar system, making it the eldest planet. Saturn formed shortly after, amassing less material since Jupiter gobbled such a large portion of the outer disk.

How cold is the moon?

Taking the Moon’s Temperature Daytime temperatures near the lunar equator reach a boiling 250 degrees Fahrenheit (120° C, 400 K), while nighttime temperatures get to a chilly -208 degrees Fahrenheit (-130° C, 140 K). The Moon’s poles are even colder.

Is the Moon 235000 miles away?

On average the moon is 380,000 km (235,000 miles) from the Earth, a distance of about 110 times its own diameter.

Can a human walk around the Moon?

A 2014 NASA study looked at the theoretical maximum walking speed on the Moon, finding that you could walk at 5km/h before you would need to break into a loping run. At this speed, you would travel the 10,900km circumference of the Moon in 91 days of non-stop walking.

What would happen if the Moon was 1000 miles closer?

If the satellite were slightly closer, the tidal bulge would grow. Low tides would be lower and high tides would be higher and any low lying coastline would be flooded. If the Moon got much closer, say 20 times closer, it would exert a gravitational force 400 times greater than what we are used to.

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.
