The Solar System

Fusion reactions occur in the cores of stars, including our Sun, where temperatures are extremely high, on the order of millions of degrees Celsius. No other location in the solar system has temperatures high enough to sustain fusion reactions.

The Kelvin scale is used for measuring temperature. In the context of the solar system, temperatures are measured in Kelvins. For example, the surface temperature of planets and other celestial bodies is often given in Kelvins.

It is the theory in which the earth is the center of the universe and that all the planets revolve around it including the sun. this theory was developed by Aristotle.
Geocentric theory basically stated that the Earth was at the center of the universe, and that the sun, moon, planets, and other heavenly bodies revolved around it. This theory was believed extensively during the middle ages.

He did not actually go to jail, but his activities were severely restricted by the Roman Church, which then had real power in government and law.

The Catholic Church didn't like his conclusions about the theories of Copernicus. This was mainly based on early texts quoted in the Bible that stated that the Earth was immovable. Galileo was convicted of heresy in 1633 and spent the rest of his life under house arrest.

******************************************

Galileo promoted the Copernican system with the Sun at the centre. The Vatican said it was OK to promote it as a way of modelling the movements of the planets, but he could not say it was the absolute truth unless there was proof. He continued saying it was the absolute truth and depicted the Pope as an idiot in one of his books, so was put on trial, and when the crunch came he was asked for proof of what he was saying, but he had no proof and he recanted. Proof did not come for another 200 years when the concept of kinetic energy had been invented in the 1800s. The story of the Catholic Church suppressing truth was convenient at the time to Protestant propagandists.

In a sense. The planets all orbit the sun because it contains about 99.9% of the mass of the solar system. The sun wobbles somewhat due to the gravity of the planets, but does not move very far.

The gravitational force of the sun is strongest for the reason that the sun is the most massive. Gravitational force is proportional to mass; the higher the mass, the stronger the gravity.

The sun has over a thousand times the mass of the next most massive object in the solar system (Jupiter).

There is a device called a wobble detector. This device measures the wobble of a star because of planets orbiting it. The reason this works is because the earth does not orbit the sun. They both orbit each other. Because the sun is so much more massive than the earth, the center of the orbit is very close to the sun. It is much easier to see this with Pluto and Charon. Charon is about half of the size of Pluto, so the center of orbit would be about one third from Pluto.

The largest planet in the Solar System is Jupiter and I'm not sure how large Jupiter is but ask someone that knows or just Google it.

Some popular theories suggest aliens may come from the Pleiades star cluster, Sirius star system, or the Orion constellation. These locations have been linked to various UFO sightings and alien encounters in the past. However, it's important to note that there is no concrete evidence to support these claims.

Cirrus clouds form by the uplift of warm, moist air along an incline of cooler air ahead of the front, for example a warm front. They are so wispy because they are actually ice crystal clouds that form at high altitudes in the upper troposphere. There are 3 types of cirrus clouds: 1. Warm Front Cirrus - Form out ahead of an approaching warm front and are blown around by upper level winds that give them their wispy appearance. 2. Anvil Cirrus - Form off of thunderstorm anvils and can signal that a thunderstorm is nearby. 3. Mares Tail Cirrus - Cirrus clouds that are blown around by upper level winds such that they look like mares tails. Hope this helps! :)

It is planet Pluto.

There are five "dwarf planets" in our solar system, as of August 2010. There are certainly dozens or hundreds more in the distant parts of our solar systems, but our telescopes are not yet good enough to see them.

Pluto was considered a planet until the International Astronomical Union (IAU) reclassified it.

Ceres was an asteroid before the IAU reclassified it.

The Kuiper Belt Objects later named Eris, Haumea and Makemake were all considered to be candidates for being named the "Tenth Planet" until the IAU came out with its definition of "planet". In fact, it was the discovery of the dwarf planet Eris, originally called "Xena", that caused the IAU to finally come up with a formal definition of "planet". All three of these objects are now considered to be "dwarf planets".

There are several other large asteroids that probably deserve "dwarf planet" status as well; Vesta, certainly, and Pallas, and perhaps a few others.

A comet

The longest river in the solar system is thought to be the Vid Flumina on Saturn's moon Titan. It is around 400 km (250 miles) long and it flows into the liquid methane and ethane seas on Titan's surface.

When you hear a weather report that forecasts scattered showers, you might wonder what you can expect. Usually it means that some parts of your area will have rain from time to time during the day or night. Some of the rain might fall where you are, and some of it will fall somewhere else. It will be scattered through the reporting area.

Mercury is considered the driest planet in our solar system. Its thin atmosphere and proximity to the Sun make it extremely hot, causing any water present to evaporate quickly.

In some adaptations, the 8th dwarf is named "Schnubert." However, traditionally, there are only seven dwarfs in the story of Snow White.

Planets not orbiting a star but instead orbiting the galactic center are referred to as rogue planets, or nomadic or interstellar planets.

Venus is known as the "greenhouse planet" due to its thick atmosphere composed mainly of carbon dioxide, which traps heat and creates a runaway greenhouse effect. This results in extremely high surface temperatures, making Venus one of the hottest planets in our solar system.

No. There are 24 hours in a day.

On Earth, that is pretty standard, but there could be other planets with a 50 hour day. Here are the approximate day lengths (defining a day by the time it takes a planet to rotate once on its axis) for the rest of the planets in the Solar System:

Mercury: 58 Earth days

Venus: 243 Earth days

Mars: 25 hours

Jupiter: 10 hours

Saturn: 11 hours

Uranus: 17 hours

Neptune: 16 hours

Unfortunately nothing in our own Solar System comes close, but we are always finding new planets and we might find one that has a 50 hour day someday.

Two planets in the solar system have the letter "m" in their name: Mars and Mercury.

Mercury is the closest to the sun and is very hot.

Venus is the hottest planet in the Solar system; it has mini volcano's all over it with storms and lightning.

Earth has people like us and has so many lifeforms to do with plants and animals.

Mars is the planet that it thought to have aliens and other lifeforms there and has been landed on by allot of rockets.

Jupiter is the planet that is very soft. It is not firm but jello like; it has not been fit to land on by NASA because of these reasons, it is the largest planet.

Saturn has rings around it of cold air and is different colours every 1,000,000 (and over) years.

Neptune is a gas planet and is covered in helium.

Uranus has bands of clouds, storm clouds all around it.

Uranus spins differently from most planets. It seems to be tilted "sideways" instead of right-side up. At the time of Voyager 2's passage, Uranus' south pole was pointed almost directly at the Sun.

Pluto is the smallest planet in the solar system.

All planets are unique.

Copernicus proposed a sun centered solar system

Galileo supported his belief.

No, astronomers have not physically gone out of the solar system. They study space and celestial bodies using telescopes and spacecraft like Voyager 1, which has reached interstellar space but is still within the boundaries of our solar system. Astronomers rely on these tools to explore the universe beyond our solar system.
