How many miles above us is the edge of the atmosphere? From Wikipedia: Three quarters of the atmosphere's mass is within 11 km of the planetary surface. In the United States, persons who travel above an altitude of 80.5 km (50.0 miles)are designated as astronauts.

- Diagram of the layers within Earth's atmosphere. Troposphere. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region.

Miles to Kilometers Conversion There are 360 * 60 = 21600 nautical miles and equals to (21600 * 1.852 = ) roughly 40,000 kilometers which is the length of the circumference of the earth. The abbreviations for nautical mile are nm,NM or nmi. Kilometer is a metric length unit and equals to 1000 meters, 10 hectometers or 100 dekameters. The abbreviation is km.

Atmospheric Pressure: Definition & Facts And yet, that part of our atmosphere that sustains all life that we know of is, in reality, exceedingly thin and extends upward only to about 18,000 feet — just over 3 miles. And the part of our atmosphere that can actually be measured with some degree of accuracy goes up to about 25 miles (40 kilometers).n fact, 21 percent of Earth's atmosphere consists of life-giving oxygen (78 percent is composed of nitrogen and the remaining 1 percent a number of other gases). And the proportion of that 21 percent is virtually the same at sea level as well as at high-mountain altitudes.

Atmosphere of Earth The Karman kármán, line at 100 (km 62), mi or.157 % Of'earth s, radius is often used as the border between the atmosphere and outer. Space atmospheric effects become noticeable during atmospheric reentry of spacecraft at an altitude of around 120 (km 75). mihe atmosphere has a mass of about 5.15 × 10 kg, three quarters of which is within about 11 km (6.8 mi; 36,000 ft) of the surface. The atmosphere becomes thinner and thinner with increasing altitude, with no definite boundary between the atmosphere and outer space.

- 1 AU = 149,597,870.700 kilometers (or 149,597,870,700 meters). Definition: An Astronomical Unit is the mean distance between the Earth and the Sun. In 2012, the International Astronomical Union defined the distance to be 149,597,870,700 meters. Historical Background: Tycho Brahe estimated the distance between the Sun and the Earth at 8 million kilometers (5 million miles). Later, Johannes Kepler estimated the AU was at 24 million kilometers (15 million miles).

Convert 0 AU to kilometers - Conversion of Measurement Units You can view more details on each measurement unit: kilometers or AU. The SI base unit for length is the metre. 1 metre is equal to 0.001 kilometers, or 6.68458712267E-12 AU. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between kilometres and astronomical units.

Earth's interior The distance from Earth's surface to its center is about 3,975 miles (6,395 kilometers). Scientists have divided the interior of Earth into various layers, based on their composition. The crust, or outer portion, varies in depth from 5 to 25 miles (8 to 40 kilometers). Below the crust is the mantle, which extends to a depth of about 1,800 miles (2,900 kilometers).

- An astronomical unit measures 97 million miles (149,598,000 km). Which is the distance Earth's orbit is around the sun. It may be used to measure the distance to objects that are a significant fraction or greater than the distance from the sun to the Earth.

Earths Atmosphere At 120 kilometers above the Earth noticeable effects can be detected on space craft reentering out atmosphere. The Karmin line is 100 kilometers (62 miles) above the Earth. It is considered by some scientists as the boundary between our atmosphere and outer space.

Earth's Atmosphere: Composition, Climate & Weather There is no distinct boundary between the atmosphere and space, but an imaginary line about 68 miles (110 kilometers) from the surface, called the Karman line, is usually where scientists say atmosphere meets outer space. The troposphere is the layer closest to Earth's surface. It is 4 to 12 miles (7 to 20 km) thick and contains half of Earth's atmosphere. Air is warmer near the ground and gets colder higher up. Nearly all of the water vapor and dust in the atmosphere are in this layer and that is why clouds are found here. The stratosphere is the second layer.

Mars The scale height of the atmosphere is about 10.8 km (6.7 mi), which is higher than Earth's (6 km (3.7 mi)) because the surface gravity of Mars is only about 38% of Earth's, an effect offset by both the lower temperature and 50% higher average molecular weight of the atmosphere of Mars.

I. The Ozone Layer The Ozone Layer. The Earth's atmosphere is divided into several layers. The lowest region, the troposphere, extends from the Earth's surface up to about 10 kilometers (km) in altitude. The next layer, the stratosphere, continues from 10 km to about 50 km. Most atmospheric ozone is concentrated in a layer in the stratosphere, about 15–30 kilometers above the Earth's surface. Ozone is a molecule containing three oxygen atoms. It is blue in color and has a strong odor. Normal oxygen, which we breathe, has two oxygen atoms and is colorless and odorless.

Quicker alternative to IF function for multiple variables? (excel 2010) Short, simple, and no need to change your format. Index is a vlookup/hlookup function (vlookup is automatic and index is the stick in a car). Small looks at a list and the 2nd parameter looks at which rank you put, i.e. 1,2,3, etc.

How Long Would It Take To Drive To Pluto? It's called an astronomical unit, or AU, and it equals about 93 million miles. Earth obviously lives at 1 AU from the sun. Mars is about 1.5 AU. Jupiter orbits out at around 5 AU and Saturn, with its gorgeous rings, lives about twice as far out at almost 10 AU from the sun.

Earths Atmosphere Layers The exosphere is the highest layer of the atmosphere. It extends up to 10,000 km (6,200 miles; 33,000,000 ft.) above the Earth. Satellites orbit the Earth in the exosphere. The atmosphere in this layer is extremely thin and atoms and molecules of air are constantly escaping into outer space.

Circumference of the Earth The circumference of the Earth in kilometers is 40,075 km, and the circumference of the Earth in miles is 24,901. In other words, if you could drive your car around the equator of the Earth (yes, even over the oceans), you’d put on an extra 40,075 km on the odometer.

- Earth's atmosphere varies in density and composition as the altitude increases above the surface. The lowest part of the atmosphere is called the troposphere (and it extends from the surface up to about 10 km (6 miles). The gases in this region are predominantly molecular Oxygen. (O2) and molecular Nitrogen (N2).

Layers of the Atmosphere The Exosphere is the outermost layer of the atmosphere. It extends from the thermopause - the transition boundary which separates the exosphere from the thermosphere below - to 6,200 miles (10,000 km) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth.

What is the mesosphere made of? The portion of the atmosphere from about 50 to 80 kilometers (31 to 50 miles) above the surface of the earth, characterized by temperatures that decrease from 10°C to -90°C (50°F to -130°F) with increasing altitude.

- These are the layers of the atmosphere, starting from the ground: 1  Troposphere - Starts at the ground. Ends somewhere between 0 to 18 kilometres (0 to 11 miles). 2  Stratosphere - Starts at 18 to 50 kilometres (11 to 31 miles). Ends at 50 kilometres (31 miles). 3  Mesosphere - Starts at 50 kilometres (31 miles).
