What would happen if you woke up one morning and there was no more atmosphere?

Without the atmosphere, there would be no air to breathe, resulting in lack of oxygen needed for survival. Additionally, the atmospheric pressure keeps liquid water stable, so it would start to evaporate rapidly. Extreme temperatures would also prevail with no atmosphere to regulate heat distribution. Essentially, life as we know it would cease to exist.

Why do you think the solar system is name solar?

The term "solar" is derived from the Latin word "sol," which means sun. The solar system is named after the sun because it is the central star around which all the planets, moons, asteroids, and other celestial objects revolve.

Did the church like ptolemy's view of the solar system?

Yes, the Church generally accepted Ptolemy's geocentric view of the solar system during the Middle Ages. This view placed Earth at the center of the universe and was in line with the Church's teachings at the time. It was not until the work of Copernicus and Galileo that heliocentrism became more accepted.

What are leftover debris from the formation of the solar system They are large bodies of tiny particles and glowing gases?

The leftover debris from the formation of the solar system are asteroids, comets, and meteoroids. These are remnants of the material that created the planets and other celestial bodies in our solar system. They exist in the form of rocks, ice, and dust left over from the early stages of the solar system's evolution.

Which planet in our solar system is cloest to the sun?

Mercury is the closest planet to the sun in our solar system.

Who on his deathbed in 1543 published his theory that the sun is a motionless body at the centre of the solar system?

Nicolaus Copernicus published his theory that the sun is a motionless body at the center of the solar system on his deathbed in 1543. This theory is known as the heliocentric model, which places the sun at the center of the solar system with the planets orbiting around it.

What do you call the third path of a planet around the Sun or a satellite around a planet?

The third path of an object orbiting another is known as a heliocentric orbit around the Sun or a geocentric orbit around the Earth. It follows an elliptical trajectory, with the object moving in a curved path due to the gravitational pull of the larger body it orbits.

Is a meteoroid smaller than a meteorite?

A meteorite by definition has reached the ground. Mist meteoroids burn up in the Earths atmosphere. Any meteorite would have been bigger as a meteoroid as the outer coating would have been burnt off during entry.

Which planet was made a non planet?

Most recently that would be Pluto. But Pluto was not the first object called a planet to be later demoted. The asteroid Ceres was known as a planet for a longer period of time than Pluto was.

What are the eight planets and what do they do in the solar system?

The 8 planets are: Jupiter, Saturn, Uranus, Mars, Venus, Mercury, Neptune, and of course our planet, Earth. Their is another planet called Pluto but NASA claimed it as 'not to be a planet' because it is too small.

All the planets are round and are spinning around. While spinning, they orbit around the Sun. Mercury takes 88 days to go around the Sun, making it the fastest out of all the planets in the Solar System. Pluto is the slowest and takes 428 earth years. The Sun gives Earth, and all the planet, light and heat energy. The planets near the Sun are much hotter than Earth. The planet farther from the Sun are much, much colder. You can find Mercury, Venus, Mars, Jupiter and Saturn in the night sky. They look like bright stars. However they do not make light like the stars. We can see them because they reflect the light of the Sun. To see Uranus, Neptune and Pluto you need a telescope because they are so far away.

What is the biggest satellite in the solar system of?

Ganymede, a moon of Jupiter, is the largest natural satellite in our solar system. But you could argue that Jupiter is the largest as it is a satellite of our sun. You could also argue that our own sun is a satellite of the galactic centre.

Which planets are small solar system bodies?

The eight planets of our system are not considered small solar system bodies, to qualify as a planet in the first place means that they have to be quite large. Small solar system bodies are such things as comets, asteroids, meterorids, moons or minor planets.

How far in km does light travel in one hour?

1,079,252,850 km

or in other words a very very long way

Why planets' orbits are elliptical and not circular?

The solar system condensed out of an interstellar dust cloud; the original cloud was not a perfectly symmetrical object, either in shape or in composition, and as it condensed, the result was not neat or orderly; there were lots of collisions as well as near misses that altered planetary orbits.

What are scientist who study the solar system called?

I'm not THAT sure...so...Just a guess here, okay?

Copernicus started the whole heliocentric idea. Then, Kepler founded about the eliptical orbits, and famous Galileo published his Dialogue Concerning the Two Chief World Systems.

How many solar panel can generate 1 mega watt?

it depends on your solar panels, i can tell you if you know the amperage and the volts, you can find the amount of watts it produce, the equation is watts = amps x volts. hate to give you an equation as an answer

What makes a solar system a solar system?

A star is all that's required.

A solar system is made of at least one star, and the star has to be big enough to have gravity strong enough to bring other objects such as gas and rock and ice into it's orbit.

What happen to Pluto in the solar system?

Pluto was declared not a planet because it didn't obey one of the three rules that i needed to obey to be a planet. It had to clear its orbits, which Pluto didn't because of its minuscule size. Pluto is approximately the size of half the United States. Also Pluto wasn't the only Pluto floating around in our solar system, apparently there are other kuiper belt objects even bigger than Pluto that are not declared planets. If Pluto was a planet these other Pluto like objects would be too. I hope this helped you!

How did terrestrial planets get there name?

Terrestrial planets got their name because they have solid surfaces similar to Earth. The word "terrestrial" is derived from the Latin word "terra," which means Earth. These planets are Mercury, Venus, Earth, and Mars.

Do all eight planets have an axis?

Yes, all 8 planets along with planetesimals like Pluto revolve around and axis.

How long does it take a astronaut to travel around the earth?

It depends on the given orbit, but most astronauts would be on near earth orbit vehicles like the International Space Station (ISS). This orbits the earth once every 91 minutes.

What is the second largest asteroid in the solar system?

Depending on what you view as an asteroid. The second largest non-Dwarf Planet KBO is 2007 OR 10 (this is a fairly newly discovered object and is based on some guesswork) falling just behind Sedna. The second largest non-Dwarf Planet in the main asteroid belt is Vesta which falls only slightly behind Pallas. However, Vesta has more mass.

Why are the first four planets in your solar system rocky and the rest gas gaints?

Because of the initial expansion of the Sun when it reached nuclear fusion. This pushed the lighter elements away from the new Sun, leaving behind the rocky and heavier elements which became the terrestrial planets. The lighter gases flowed passed the "ice line" [See related question] where it was cold enough for molecules to combine into the Gas and Ice giants.

Why was Dagobah called a system instead of a planet?

Dagobah was the name of the star around which the planets, including Yoda's planet, revolved.

The planet Yoda exiled himself to was an unnamed and unexplored planet. Yoda selected this planet because of it's remoteness and lack of population. The planet's star was named Dagobah, so all the planets revolving around the star were part of the Degobah system.
