The Solar System

A typical solar granule is about the size of a small state, such as Texas, on Earth. They are roughly 1000 kilometers in diameter and form the visible surface of the Sun.

Venus is the hottest planet in our solar system due to its thick atmosphere that traps heat. Its average surface temperature is around 465 degrees Celsius (869 degrees Fahrenheit), making it hotter than Mercury, even though it is further from the sun.

1. Collapse of a giant molecular cloud: Gravity causes a cloud of gas and dust to collapse under its own weight.
2. Formation of a protostar: The collapsing cloud forms a protostar at its center due to increased pressure and temperature.
3. Accretion disk formation: Surrounding material forms a disk around the protostar from which planets and other celestial bodies will eventually form.
4. Planet formation: Dust particles in the disk collide and stick together, gradually forming planetesimals that will eventually accrete into planets.

Venus is so hot because of a number of things.

It is closer to the Sun than Earth but that is not the main reason.

Venus has a massive amount of carbon dioxide (green house gas) in it's atmosphere which prevents solar radiation from being released back into space. So every day, energy from the Sun is absorbed by the planet but is not released back into space.

Venus is an example of "global warming" gone mad.

If we are not careful, this could be the fate of our Earth.

Before planets began to form, the inner 0.3 AU of the solar system likely contained a mix of volatile compounds such as water, carbon dioxide, methane, ammonia, and other organic molecules. These substances would have been present in the protoplanetary disk from which the planets eventually coalesced. The intense heat and radiation in this region would have prevented the condensation of solid particles, leading to a primarily gaseous composition.

the closer the smaller orbit (a year is one complete orbit) so the year is smaller

Uranus is the 7th planet from the sun in the solar system

Saturn is the sixth planet from the Sun and is known for its distinctive rings made of ice particles and rocks. It is a gas giant, primarily made up of hydrogen and helium. Saturn's gravity plays a role in maintaining the structure of the asteroid belt and protecting Earth from potential asteroid impacts.

The heavy bombardment phase of the solar system lasted from about 4.1 to 3.8 billion years ago. During this period, the inner planets, including the Earth, experienced intense impacts from leftover debris in the solar system. This phase played a crucial role in shaping the surfaces and atmospheres of these planets.

it depends if you mean one that was in the asteroid belt if so then its about 3AU away and if earth is about an AU away from the sun then i would say it takes around 2 to 5 earth years to make one full revolution.

No, the Moon generates no light of its own. However, it reflects the light of the Sun, so when you see moonlight you are actually seeing reflected sunlight.

(They apparently didn't think about that when they created the vampire legends. If sunlight kills vampires and moonlight is just reflected sunlight, why doesn't moonlight kill vampires, too?)

OF course Mercury, the closest planet to the sun.

From that vantage point, you would observe the planets orbiting the Sun counterclockwise. The orbits will be nearly in the same plane, known as the ecliptic plane. Also, you would see that inner planets move faster in their orbits compared to outer planets.

The fifth largest moon in the solar system is The Moon on Earth.

OK. Let's say that all times are compressed by a factor of 13 billion. Let's just go right ahead and say that.

Now let's take the high point of Galileo and Kepler to be roughly 500 years ago.

500 years . . . which is 1.5778 x 1010 seconds . . . when compressed by a factor of 13 billion . . .
compresses to 1.214 seconds ago.

The oldest objects in the solar system whose age has been measured are small grains of dust known as calcium-aluminum-rich inclusions (CAIs) found in meteorites. They are believed to have formed within the first 2-3 million years of the solar system's history. This makes them some of the oldest solid materials known in the solar system.

The astronomical event that corresponds to the passage of one month is the cycle of the Moon completing one orbit around Earth, which takes approximately 29.5 days. This cycle results in the phases of the Moon changing from new moon to full moon and back again over the course of a month.

There are many myths that tell this story. Linguistically, however, the English word "sun" comes from Old English (Anglo-Saxon) "sunne," which in turn came from Germanic "sunno." All of these words meant "sun."

Also,Germanic "sunno" came from the Indo-European word "suwen" or "sawen," which was an alternate form of the Indo-European word "sawel," which meant "to shine" or "the sun." The origin of the name "Sun" is probably at least three thousand years old, because it can be traced back all the way to the Indo-European language, which is the ancestor language to many languages of today, including English, French, German, Spanish, Greek, and Persian. There is no hidden or other meaning to the name "Sun": It is just the name of that big bright light that is in the sky during the day. the sun does mean that but it means something else also. (Edit by Lolzylooz) The saxon/germanic/danish goddess of the sun was known as sunna. It is unknown who firstnamed the sun, but this is my guess. Sorry i can't be of any more help. xVx

The nebular hypothesis is important in explaining how the solar system formed from a rotating cloud of gas and dust. It provides a framework for understanding the formation of planets, moons, and other celestial bodies through gravitational collapse and accretion processes. This hypothesis helps scientists study the properties and composition of our solar system and other planetary systems in the universe.

Neptune stays in orbit around the Sun due to the gravitational pull between the two bodies. The Sun's gravity keeps Neptune in its orbit, just as it does for all the other planets in the solar system. This balance between the Sun's gravitational pull and Neptune's orbital speed keeps it from moving away or falling into the Sun.

The hottest part of the solar system would certainly be within the sun. The core of the sun is estimated to exist at a temperature around 15,000,000 K. The solar envelope surrounding the core averages more around 4,000,000 K. The photosphere (the layer we get out light from) is a much cooler 6000 K. The next layer out, the chromosphere is actually hotter - around 7000 K due to the energy it absorbs. The outermost layer, the corona, varies from 1,000,000 K to 3,000,000 K - hotter than the photosphere and chromosphere, but still cooler than the core and solar envelope.

The hottest part of each of the planets is at their core. None of the planets have cores at temperatures approaching that of the core of the sun. For example, the core of the Earth is estimated to be only 5700 K - not even as hot as the coolest part of the sun). Jupiter may be around 24,000 at its core, Saturn around 12,000 K, and Uranus and Neptune around 5000 K.

Despite being closest to the sun, temperatures on the surface of Mercury only rise to a (compared to solar temperatures) balmy 427 °C (700 K) at closest approach to the sun on the side facing the sun. Venus actually has higher surface temperatures - close to 735 K due to the thick atmosphere and runaway greenhouse effect.

The gravitational attraction between the sun and the planets causes them to follow an elliptical orbit at varying speeds, dependant on the planet's mass and distance from the sun.

comets are on the outside of the solor system but loop in from the sun

I believe from astronimical studies in 8th grade, (which my annoying science teacher practically crammed down my throat for a couple of months) there is a large belt of comets just past Pluto.
