The Solar System

Initially, 5 billion years ago, a large collection of Hydrogen gas accumulated over time to form a large body of gas. When temperature gets extremely high in the core of this body, nuclear fusion starts, using the gas as fuel. So, there was already gas in the first place, and the star dies when this fuel runs out.

An Astronomical Unit (AU) is the average distance between the Earth and the Sun.

Copernicus's concept of the solar system was influenced by the ancient Greek astronomer Aristarchus of Samos, who proposed a heliocentric model in which the Earth and other planets revolved around the Sun. Copernicus built upon this idea and formulated his own heliocentric model in the 16th century.

According to those who do not accept the IAU's judgement on such matters - and no one is required to - Pluto.

While Pluto was declared by the IAU to no longer be a planet, many disagreed. They had - and have - that right.

4, all the big planets have rings. Saturn,Uranus,Jupiter,and Neptune.
Four
Four of the planets in the solar system have rings. The 4 gas planets have rings which are Jupiter, Saturn, Uranus and, Neptune. It was not until 1970 that the gas planets had rings. The rings on Saturn are a lot brighter then the other gas planets

Earth is the third closest planet to the sun.

Jupiter is the first of the outer planets. The asteroid belt separates the inner and outer planets.

Heliocentric theory is a model of the solar system that places the Sun in a central place, with the planets orbiting it.

The two main parts of our solar system are the inner solar system, which includes the Sun, Mercury, Venus, Earth, and Mars, and the outer solar system, which includes Jupiter, Saturn, Uranus, Neptune, and various dwarf planets like Pluto. The inner solar system is closer to the Sun, while the outer solar system is farther away.

It seems like you may be mixing up different concepts. J.R.R. Tolkien was an author famous for "The Lord of the Rings" series, Jerry Lewis was a comedian, Barney is a fictional purple dinosaur, and beer is an alcoholic beverage. These concepts have no direct association with the solar system.

The sun holds celestial bodies in the solar system through its gravitational pull. This gravitational force keeps planets, moons, asteroids, and other objects in orbit around the sun. The balance between the sun's gravity and the forward motion of the celestial bodies keeps them moving in stable orbits.

The primary source of energy in our solar system is the Sun. It generates heat and light through nuclear fusion, which impacts all the other celestial bodies in the system. Other sources of energy within the solar system, such as geothermal energy on certain planets or moons, are secondary to the Sun's influence.

All planets in our solar system revolve (or orbit) around the Sun in an anticlockwise direction - the same direction that Earth spins (daily rotation) as seen by an observer looking down from above Earth's north pole.

Since known plants in the solar system all grow on Earth, they too would be compelled to orbit the Sun in the same direction as Earth.

Yes, all recognized dwarf planets are part of our solar system. This category includes objects such as Pluto, Eris, Haumea, and Makemake. They are celestial bodies that orbit the Sun but have not cleared their orbital path of other debris like a regular planet.

Many comets are believed to be largely composed of water ice, with some other amounts of silicate (rocky) components, fragments or dust - such that they earned the nickname "dirty snowballs."

The most common way is to use a Radioactive Thermoelectric Generator (RTG). As you may know, thermoelectric devices allow a small amount of electric power to be produced using thermal energy from a source of energy. In fact they are just developments of the simple thermocouple used to measure temperature electronically. For space use, where the device has to operate perhaps for some years without any fuel being supplied, radioisotopes offer one way to provide this heat source. The most commonly used source is plutonium 238, which gives off alpha radiation and is therefore easy to shield. The following extract from Wikipedia gives a summary: the full article is given as a link below.

A common application of RTGs is as power sources on spacecraft. Systems Nuclear Auxiliary Power Program (SNAP) units were used especially for probes that travel far enough from the Sun that solar panels are no longer viable. As such they are used with Pioneer 10, Pioneer 11, Voyager 1, Voyager 2, Galileo, Ulysses, Cassini and New Horizons. In addition, RTGs were used to power the two Viking landers and for the scientific experiments left on the Moon by the crews of Apollo 12 through 17 (SNAP 27s), excluding Apollo 13 because that mission never reached the Moon's surface. RTGs were also used for the Nimbus, Transit and Les satellites. There have also been some nuclear reactors put into space, both US (SNAP-10A) and Russian (RORSAT), but these can now be considered historical, I don't think there is any current use. Links to articles are given below.

Mercury is the closest planet to the Sun in our solar system, orbiting approximately 36 million miles away from it. It is the smallest and innermost planet, taking about 88 Earth days to orbit the Sun.

Uranus is the 7th planet from the Sun and the 4th largest planet in our solar system, after Jupiter, Saturn, and Neptune. It is an ice giant with a diameter of about 50,724 kilometers, making it slightly larger than Neptune.

The gas giants in our solar system are Jupiter, Saturn, Uranus, and Neptune. These planets are primarily composed of hydrogen and helium, and they have thick atmospheres of gas surrounding a solid core.

acceleration together a = (G*(m1+m2))/r^2 balanced by:

acceleration apart a = v^2/r

G = 6.67*10^-11 (m^3-kg^-1-s^-2)

m1 = mass 1 (say sun = 1.9891*10^30kg)

m2 = mass 2(say earth+moon= 6.048*10^24kg)

r= distance between cog's (metres)

v= orbital velocity (metres/sec)

gravity/distance/orbital velocity are all complimentary

The best view of the solar system is that from either of the two Voyager spacecraft which show the solar system from outside.

The modern view of the solar system is that there are 8 planets orbiting the Sun.

There are also a lot of smaller bodies orbiting the Sun. They are mainly the dwarf planets, asteroids, Kuiper Belt objects, and comets.

It's going to be difficult to make an actual model. The problem is sizes and dimensions. The Sun is 400 times further away from the Earth than the Moon is, and it has about 110 times the diameter of the Earth (which is itself around 4 times the diameter of the Moon), so if your "Sun" is an ordinary light bulb, your "Earth" is going to be very small and your "Moon" is going to be almost invisibly tiny. Also, the Moon is separated from Earth by a little over 30 times the Earth's diameter, and remember the Sun is 400 times further away than that.

That said, you could cheat a little on the scales. Get an R-type bulb (which gives off a more directional light, as if it had come from further away), a styrofoam ball for Earth, and another one around a quarter that size for the Moon. Mount the bulb as far as you can conveniently get it from the "Earth", and adjust the location of the "moon" so that it casts the proper kind of shadow (that is: there should be a dark spot in the middle, and a lighter grey shadow around it). The accompanying poster should explain that the model is not to scale for the reasons stated in the first paragraph (you'd need a light bulb the size of a car on the other side of the gym if you wanted to get the scale right).

There is no known word in the solar system that has the sequence "nomsrterao." It appears to be a random combination of letters that does not correspond to any astronomical term or object.
