The Solar System

Saturn has long been known for its ring system but more recently rings have also been discovered around Jupiter, Uranus and Neptune.

Earth is unique among planets in our solar system because it has liquid water on its surface, which is essential for supporting life as we know it. It also has a diverse range of ecosystems and a protective atmosphere that shields it from harmful solar radiation. Additionally, Earth has a strong magnetic field that helps protect it from solar winds.

The orbit closest to the sun is the smallest. That distinction belongs to Mercury.

That depends upon who you are. Earth is pretty special to most of us. Saturn looks way cool through a telescope, however. Those rings are quite pronounced, and beautiful. Jupiter is the biggest, of course, and contains that wondrous red spot storm.

Arguments could be made for the others, but I think I'd rank them Earth first, and Saturn a close second.

Hindu mythology contains various stories and symbols that are connected with celestial bodies in the solar system. For example, the planets are often personified as deities in Hindu mythology. Additionally, Hindu cosmology includes concepts such as the cyclical nature of time and the movement of celestial bodies influencing human life.

The heliocentric model proposed by Nicolaus Copernicus and further developed by Johannes Kepler and Galileo Galilei is largely accepted today. This model places the Sun at the center of the solar system with the planets, including Earth, orbiting around it.

The planets are either inner or outer planets.

There are 8 planets.

And of those eight planets: Mercury, Venus, Earth, and Mars are the inner planets.

While: Jupiter, Saturn, Uranus, and Neptune are the outer planets.

Within the solar system the most common method of observing objects that are at a great distant from the Earth is through the use of conventional Optical Telescopes. The Kuiper Belt, the farthest observed edge of the Solar System (although not the limit of), has been viewed using the Hubble Space Telescope (HST), of Newtonian Design. The objects in this belt have both been viewed in optical wavelengths and infrared using the HST.

-- On the smallest scale, the Earth and moon both revolve around their common

center of mass. Since the Earth is roughly 80 times as massive as the moon, that

common center of revolution is inside the Earth.

-- On the next larger scale, the Sun, and that common center of the Earth/Moon pair,

both revolve around their common center of mass. Since the sun is roughly 329,000

times as massive as the Earth/Moon pair, that common center of revolution is inside

the sun.

-- On the next larger scale, the Sun, and everything gravitationally bound to it, known

as the "Solar System" and including the Earth, revolves around the common center of

mass of itself and the rest of the Milky Way galaxy. Since the Milky Way Galaxy as a

whole may be as much as 400 billion times as massive as the solar system, that common

center of mass is essentially at the exact center of the galaxy.

The second most abundant element in the solar system is hydrogen.

The only celestial (stellar) body in our solar system is our sun. The other bodies are all terrestrial objects--planets, comets, asteroids, moons, and such. Some may shine a bit in the infrared from the decomposition of radioactive isotopes within them, but all optical brightness is simply reflected sunlight.

every thing has certain age ,our sun,and earth will also have certain age of thousands of years, so after that where did our futures will live?

adding to that out planets may be more developed or richer than us.

so new planet is new chance for new life...................

All massive bodies in the solar system are in motion, even the Sun. The planets occupy elliptical paths with a common center of gravity with each other and the Sun (barycenter) at one of the foci of the ellipse, the path being called an orbit; the motion of the planets in the orbit is counterclockwise as seen from above the Earth's north pole looking down at the orbits and per Kepler's laws at its closest approach to the sun will move slightly faster and at greater distance moves slightly slower - this effect also consistent with the length of the orbital period or year, increasing distance resulting in longer years. The axis of the ellipse also precesses or advances slightly with each orbit (per predictions of Einstein's General Relativity). Other bodies not in orbit directly around the Sun may be in orbit around a planet and orbit their primary while the latter is in solar orbit. Some objects such as comets have highly elongated orbital paths. All objects also have some intrinsic angular momentum, rotating on their own axis (day). All objects interact and are drawn by other objects to a greater or lesser degree mediated by the force of gravitational pull proportional to mass and inversely proportional to the square of the distance; these effects creating irregularities in their orbits (perturbations) some of which result in stable harmonics known as orbit resonance. Spin-orbital resonance may also arise from tidal force and affect the relationship between rotational and orbital periods.

There are other types of motion but these are some of the basics.

Solar thermal heats water directly from the sun in panels called solar collectors. Fluid is pumped though the collectors and gets up to about 200 degrees F. That heat is then transferred to a storage tank, either directly in warm climates or through a heat exchanger in climates that freeze, as the hot fluid can be mixed with non-toxic antifreeze. For domestic hot water, that's about it, you just use the hot water in the tank for your showers and washing. For heating the house, you can either use the hot water for radiant floors, convection fan heaters, or forced hot air through a water to air heat exchanger.

No one currently lives on Pluto as it is a dwarf planet located in our solar system. It is far from Earth and extremely cold with no known atmosphere that could support human life. Any future exploration missions to Pluto would likely be performed by spacecraft rather than humans.

1. Asteroids: Small rocky objects that orbit the Sun, mainly found in the asteroid belt between Mars and Jupiter.
2. Moons: Natural satellites that orbit planets in the solar system, such as Earth's moon or Jupiter's moons.
3. Comets: Icy bodies that originate from the outer regions of the solar system and have highly elliptical orbits that bring them close to the Sun.

Islam doesn't forbid astrology but doesn't call Muslims to believe in their sayings or predictions. Only God knows the future. All the astronomers are not saying absolute truth even if their predictions come true.

That all depends on how you build the list. If you line them up in the order of greatest mass, smallest density, length of rotation period, or equatorial diameter, then I don't know the answer to any of those. But if you line them up in the order of their average distance from the sun, starting with the smallest distance, then the third one on that list is Earth.

One of the key figures who challenged the geocentric model of the solar system was Nicolaus Copernicus, who proposed a heliocentric model with the Sun at the center and the planets, including Earth, orbiting around it. This heliocentric model eventually gained acceptance and revolutionized our understanding of the solar system.

Jupiter, Saturn, Uranus, and Neptune have rings, but only Saturn's are easily visible from Earth. Compared to Saturn's prominent disk, the rings of other planets are thin, narrow, and ill-defined.

Energy in a passive solar system is collected by materials in the building structures, such as walls, windows, and floors, that absorb and store solar heat during the day and release it at night to heat the space. No mechanical or electrical devices are used to collect or distribute the energy.

The greatest inaccuracy in Copernicus' model of the solar system was that he still believed that planets moved in perfect circles, when in fact they move in ellipses. This led to inaccuracies in predicting planetary positions.

Scientists hypothesize that the sun formed from a giant cloud of gas and dust in space, known as a solar nebula. As gravity caused the nebula to collapse, most of its material gathered at the center to form the sun, while the remaining material formed the planets, moons, and other objects in the solar system. This process is known as the nebular hypothesis.
