The Solar System

The lower mantle is the portion of the Earth's mantle layer that extends from a depth of 670 km to 2798 km from the surface. Minerals present in the rock of the upper mantle become unstable at these depths. Little is known about the lower mantle other than that seismic waves indicate it is fairly homogenous in lithology and therefore density.

Deimos, Mars' moon, is the smallest known moon. Its mean diameter is approximately 12.4 kilometers (8.8 miles).

Approximately 21,993,756 Deimos' can fit inside our Moon, or 8,709,208,240 Deimos' can fit inside Earth.

It's a "terrestrial" planet, because it is rocky with an iron core, like planet Earth. "Terrestrial" means "Earthlike".

Jovian planets are mainly made of gases

and liquefied gases.

Saturn.

This is untrue. Both Mercury and Venus have shorter orbits and therefore take less time to orbit the Sun, because they are the two planets closer to the Sun then Earth. Saturn is further from the Sun and takes much longer to orbit it.

Gravity compresses gases at the center of a solar nebula until temperatures are high enough for nuclear fusion to occur.

It doesn't 'DO' much. It is a region between Mars and Jupiter where asteroids orbit The Sun.

The Greek model of the solar system was developed by one Claudius Ptolemy.

Gravity plays a central role in causing gas to come together in clouds and gradually form dense clouds that eventually generate heat and then start up a nuclear reaction - a star. Gravity also causes rocks to clump together to form planets, and then it holds those planets in orbits round the star that they are close to, to form solar systems.

The sun was likely created about 5 billion years ago along with the Earth and later the moon. Because it is not a SOLAR system without a sun, this means that the solar system itself was created around this time

It is impossible to answer.

The visible Universe is about 13.7 billion light years across and getting larger with every year.

The Solar System is a mere 2 light years at most, a mere 6'850'000'000 of that number.

It was not an immediate improvement and actually it used more epicycles than the Ptolemaic mode so was more complicated.

But the idea that the Sun is at the centre was taken up by Kepler in his studies of planets' orbits that led to the laws of planetary motion and eventually to the dynamic model of the solar system devised by Newton and others, which is the generally accepted model at the present time.

"2.11 degrees" is the sort of number that's sometimes given. However, most sources now say that the tilt is probably less than one degree. Either way, it's

the smallest tilt of any planet.

Five official dwarf planets are currently recognised by the IAU.

Ceres (in the asteroid belt between Mars and Jupiter) is the smallest, then Haumea, then Makemake, then Pluto and finally Eris, which is the largest.

There are several other candiates, but these cant be confirmed as official dwarf planets until their shape can be determined.

This is a rather simple answer. Mercury travels around the sun faster than Venus because it is closer to the Sun. In order for Mercury to be able to be a planet it has to remain a certain distance away from the sun or be dissolved. Mercury is that distance and as a result when it orbits it's Orbital time is significantly less than Venus which is a lot farther away.

For example if you had a friend stand still they would represent the Sun, if you had another friend stand two to three feet away (not to scale) they would be Mercury. Then have another friend stand probably ten feet away from the sun (again not to scale). Then have both friends walk around the friend who represents the sun, the person who is Mercury will have a much smaller circle to walk.

No. Nothing will always exist. All atoms exhibit some measure of radioactive decay, and black holes decay via Hawking radiation, so eventually there will be absolutely nothing left in the universe. This will take a stupendously, ridiculously, incomprehensibly long time -- approximately a googol years.

Fancy boy

Solar means our sun and all the 8 planets orbiting around it and other dwarf planets forms a system . that's why it is called so. Also the mass of sun is about 99.86% of the total mass of solar system . So Sun is the head of our family .

The Earth is estimated to be around 4.5 billion years old, while the solar system is thought to have formed around the same time. This estimate is based on radiometric dating of meteorites and rocks from Earth.

No. But given time - a long time - it is likely that Venus will have a 1:1 orbital resonance with the Sun.

No, the sun is a star, not a planet. The hottest planet in the Solar System is Venus, coming in ahead of Mercury due to its thick atmosphere of mostly CO2 being able to hold in heat extremely well.

Well first of all, since the planets are almost perfect spheres, they have no 'sides'.

You're probably thinking of Uranus, whose axis of rotation is tilted of 97.77°, and
so is approximately parallel with the plane of the Solar System.

The name "solar" says it all - "solar" means SUN. IT has ALWAYS been recognized that the SUN is the center of the "solar system".

Perhaps you meant to ask a different question - like "what was the belief BEFORE the recognition of the heliocentric (solar system) model?" - in which case the answer would be that the EARTH - particularly the Vatican in Rome was believed to be the center of the Universe.

Yes. The solar system is everything that orbits the sun.
