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.
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.
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?
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.
