The Solar System

All of it - to - a single photon.

well it occurs in the core of the sun, and it travels because it is shot out of the sun because it has too much pressure.

We don't know if places in our own solar system that are thought to be capable of sustaining life have life; there's no way we could possibly know about a planet dozens of light years away.

I am not sure that the word "strong" can be applied meaningfully to a planet.

Venus.

The "day" (rotation period or sidereal day) is longer than the year!

Venus Sidereal day: 243 Earth days.

Venus Year: 224.7 Earth days.

Mars is the inner planet farthest from the Sun.

The 'Nebular Hypothesis', proposed by German philosopher Immanuel Kant (1724 - 1804) and developed by French scientist Pierre LaPlace (1749-1827), states that a huge gaseous nebula contracted and became us.

As for the configuration: The original, posited by virtually every civilization and championed by Ptolemy, was the 'Geocentric' pattern - placing the Earth in the center. After Galileo and Copernicus, it was updated to the 'Heliocentric' pattern (circling the sun) which we adhere to today.

The years represent planets going around the sun.

It would be HIGHLY unlikely; Halley's Comet doesn't intersect Earth's orbital path at any point. It's possible that someday in the distant future Halley's Comet might get close enough to Jupiter or Saturn to be tugged into a collision orbit, but at the moment we see no chance that this will happen.

It would be far more likely for Earth to be hit by some comet or asteroid that we are entirely unaware of, coming from deep space.

As far as I know, this is mainly determined by radioactive dating methods. If a rock is found (for example, from a meteor) that has a certain age according to such dating methods, then it follows that the Solar System is at least as old (assuming the rock was part of the Solar System to begin with).

William Herschel is credited with the discovery in 1781.

It seems John Flamsteed observed Uranus first, but failed to identify it as a new planet.

I believe you are confusing a solar system with a galaxy. Our galaxy contains several hundred billions stars, i.e., solar systems.

No. A celestial object is an object in outer space, such as a planet, star, meteor or comet. Clouds are not in outer space, therefore they are not a celestial object.

It's important because if we were around neptune or pluto's position we would freeze to death and if we were close to mercury we would burn to death!! hope that helped.

Only one; its gravity, which attracts everything nearby.

Oh, were you asking something like "Why should we go to Uranus?" That would be difficult to know, since it's so far away. There are no raw materials there that would be worth it to transport back to someplace warm (Uranus is VERY far from the Sun...) and we aren't sure what sorts of things might be out there.

We believe that the atmosphere of Uranus is primarily light gasses such as hydrogen, so it might be useful as a refueling stop on our way outbound from the Sun to other star systems.

it is carried by a fat man on a bike no joking it is the gravitational force that is roduced by the plantets nearest the help it to move.And from that its called a inertia the inertia lets it not go boosh in the sun, the inertia pulls it upward to the northern western axis

1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune

Gravity combined with the object's "sideways" (tangential to its orbit) motion.

The Sun "wants" to pull the object towards it and the object "wants" to fly of into space. When these two things are balanced the object is in a stable orbit.

Planet X does not exist. It was only a theory.

Gasses & dust including all known elements.

To say that black holes have infinite gravity is somewhat misleading. Theoretically, the strength of gravity at the singularity is infinite, but it diminishes with distance. While technically there is some gravitational attraction, even across light years of space, the effect is tiny at such distances.

Voyager 1 and Voyager 2 have both left the heliosphere, but neither has left the solar system. The edge of the solar system is considered to be the outer boundary of the Oort Cloud, The exact width of the Oort Cloud is not known, but its estimated that it would take Voyager 2 about 300 years to reach the inner boundary of it. To reach the outer boundary of the Oort Cloud, truly leaving the solar system, would take Voyager 2 something like 30,000 years.

From Wikipedia: "Spectroscopic analysis of Pluto's surface reveals it to be composed of more than 98 percent nitrogen ice, with traces of methane and carbon monoxide." Further down, it is believed that there is water ice, and finally a rocky core.
