The Solar System

The sun is at the center of our solar system. It makes up 99.85% of the mass of our solar system, and due to the way gravity works, this keeps it at the center and everything else spinning around it.

A good long way - about 25,000 light years or so, and thank goodness for that! There is, we believe, a super-massive black hole at the center of the Milky way (and probably at the centers of most large galaxies) and it would be very unhealthy to be anywhere near it.

Pluto is no longer a planet. Its designation has been changed to a dwarf planet.

When the moon is either 180 degrees from the sun, or aligned with it.

That is, if you could draw a straight line from the sun to the earth and out into space beyond, if the moon lands anywhere on that line, you have spring tides.

In that alignment, you'll have either a new moon or a full moon.

Our solar system consists of the sun, the planets, their moons, and a variety of smaller objects. The sun is at the center of the solar system, with other orbiting around it. The force of gravity holds the solar system together.

Nicolaus Copernicus was the sixteenth-century astronomer who proposed the heliocentric model of the solar system, demonstrating that the Earth orbits the Sun. His book "De Revolutionibus Orbium Coelestium" laid the foundation for modern astronomy.

Planet X has never been seen - largely because it does not exist.

The term "Planet X" originally referred to a hypothetical planet that lay beyond the orbit of Neptune. Due to what seemed to be irregularities in the orbit of Uranus and Neptune, astronomers, such as Percival Lowell, theorized that yet another large planet must lay even further out, causing the anomaly. The later discovery of Pluto seemed to justify the idea, but it was eventually determined to be too small to affect the gas giants. Data from the Voyager 2 mission finally put the idea of Planet X to rest when it was shown that the seeming anomalies in the orbits were due to astronomers underestimating how large Neptune was.

The sun has burned for approximately 4.6 billion years, and is expected to do so for about 5 billion more.

When it finally flares up into a red giant and then burns out, our solar system will be radically different: every planet will be freezing cold, and the planets Mercury and Venus (and probably Earth) will have been swallowed up and completely destroyed. The sun itself will have become a slowly-cooling white dwarf, with about half as much mass as it has now, compressed into an ultra-dense body about the size of Earth.

But after moving outward due to the weaker gravity of the less-massive sun, the rest of the solar system will likely settle down and endure as such until the end of time, or until another star happens to come close enough to capture some of the planets or otherwise change and destabilize their orbits.

No, the solar system is made up of 8 planets, with Pluto as a dwarf planet.

In our solar system, the planet with the lowest air temperature is Uranus, with a minimum temperature of about 49 K and a mean surface temperature at 1 bar of about 76 K.

The planets in our solar system have an elliptical (oval) orbit around the Sun. This orbital shape is a result of the gravitational forces between the planets and the Sun. Planets closer to the Sun have shorter and more circular orbits, while those farther away have longer and more elliptical orbits.

The most common type of rock in the solar system is basalt. Basalt is a fine-grained, volcanic rock that is found on Earth, as well as other planets and moons in our solar system, such as the Moon, Mars, and Venus.

No, the solar system is held together by the force of gravity. Gravity is what keeps the planets in orbit around the Sun and the moons in orbit around their host planets. Inertia is the tendency of an object to stay in motion or at rest unless acted upon by an external force.

the four biological systems are fisheries,forests, grasslands, cropland.

It is depleted because of over fishing, forest disappear for firewood, grassland and converted into barren wasteland and cropland deteriorate. Their productivity is badly affected as they are reaching now an unsustainable level. so the life support in earth os being depleted fast.

Greenhouse gases also affect the temperature on other planets in our solar system, such as Venus and Mars. Venus experiences an extreme greenhouse effect, which has led to its surface temperature being much hotter than Mercury, despite being further from the Sun. Mars has a thin atmosphere composed mainly of carbon dioxide, but its greenhouse effect is weaker compared to Earth.

The movement of planets within the solar system is primarily due to gravitational forces exerted by the sun. The sun's gravity keeps the planets in orbit around it, while their own momentum and inertia cause them to move in their respective paths. This dynamic balance of forces results in the planets' continuous motion.

The force that causes the formation of the solar system is primarily gravity. Gravity pulls particles and gases together, forming a spinning disk that eventually condenses into the Sun and planets. Other forces such as electromagnetic and nuclear forces also play a role in the formation process.

There are hundreds of Moons that are around 10 kilometers or less in diameter. Mainly in orbit around Jupiter or Saturn.

Jupiter's smallest moon is probably S/2003 J 12 or S/2003 J9 at only 1 kilometer in diameter.

Saturn's smallest moon is probably Aegaeon at only 0.5 kilometer in diameter - although it is classified as a moonlet.

If you don't want the moon to be around a planet, the Asteroid IDA (243 IDA) has a tiny moon called Dactyl which is under a kilometer in diameter.

Yes, there are moons discovered outside our solar system, known as exomoons. These exomoons are typically detected using the same techniques as exoplanets, such as transit and timing variations. While not as common as exoplanets, exomoons contribute to our understanding of celestial bodies beyond our own solar system.

The solar system consists of the sun and all the celestial objects that orbit around it, including planets, moons, asteroids, and comets. It is characterized by its vast size, with the sun being the largest object and exerting gravitational influence over everything in the system. The planets in the solar system orbit the sun in nearly circular paths on a relatively flat plane known as the ecliptic.

Albert Einstein's theory of general relativity helped us understand the bending of light by gravity, which is crucial for accurately predicting the path of light from distant celestial bodies in the solar system. This theory also provided insights into the geometry of spacetime, influencing our understanding of planetary orbits and the motion of objects in the solar system.

Earth has liquid water on its surface, a diverse range of life forms, a protective magnetic field, and an atmosphere primarily composed of nitrogen and oxygen. Other planets in our solar system lack one or more of these characteristics.

Gravity causes smaller pieces of matter, such as gas and dust particles, to come together and accumulate over time. As more material gathers together, the gravitational force increases, leading to the formation of stars, planets, and solar systems. This process is known as accretion.

A Geocentric model places Earth at the center of the Universe, with all of the stars and planets revolving around it. The most famous such model is that of Ptolemy. It stood as the accepted model until Copernicus was proven right by Galileo and Kepler.
