The Solar System

1. Mercury: Closest planet to the Sun, with extreme temperature variations and no significant atmosphere.
2. Venus: Hottest planet due to a thick layer of greenhouse gases, with a retrograde rotation and sulfuric acid clouds.
3. Earth: Only known planet to harbor life, with diverse ecosystems, liquid water, and a protective magnetic field.
4. Mars: Often called the "Red Planet," with evidence of past water, polar ice caps, and the largest volcano and canyon in the solar system.
5. Jupiter: Largest planet with a strong magnetic field, iconic Great Red Spot storm, and dozens of moons.
6. Saturn: Known for its prominent rings, made up of ice and rock particles, and large moon Titan with an atmosphere and lakes of methane.
7. Uranus: Tipped on its side, with a ring system and unique "cutting diamonds" composition in its atmosphere.
8. Neptune: Farthest planet from the Sun, with the strongest winds in the solar system and a striking blue color due to methane in its atmosphere.

The hypothetical sphere around the solar system is known as the Oort Cloud. It is a region of space theorized to contain icy objects and comets that extends far beyond the orbit of Pluto. The Oort Cloud is thought to be the source of long-period comets that occasionally enter the inner solar system.

In fact, they are. A space probe, "New Horizons", is already underway to Pluto. I don't remember the name of the mission to the Sun, but there is one, either traveling or being planned. Being as hot as it is, it won't exactly go into the Sun, but much closer than the 150M km. that Earth is from the Sun.

In fact, there are several space probes orbiting the Sun now. A couple of them are in polar orbits around the Sun, giving us a view of the Sun that we could never see from Earth, and a couple of them are 6o degrees away from the Earth in our orbit so that we can see "around" the Sun to see if there are any major flares or sunspots that are out of the view of Earth-based telescopes.

Of course, we can't send probes TO the Sun, because the probes would be destroyed - but we don't have to be really close to get a good view!

The Sun is the celestial body that undergoes nuclear fusion, where hydrogen atoms combine to form helium, releasing energy in the process.

Yes, we don't use radar to measure the distance to the Sun directly.

However, we can use radar to measure the distance to objects like the

Moon and Venus, which will reflect radar.

We can measure the Venus to Earth distance when Venus is between us

and the Sun (more or less). Then we can simply use Kepler's 3rd Law to

derive the Earth to Sun distance.

Alternatively, trigonometry can be used, once the Earth Venus distance

is known.

We can use the occasions when the Earth-Venus-Sun angle is 90 degrees.

See "related links" below for details of this.

We can also use times when the Earth-Sun-Venus angle is 90 degrees.

It's not that radio waves wouldn't be reflected by the Sun; but the Sun

_GENERATES_ so much radio energy that any reflection would be entirely

swamped by the primary signal.

Think about it this way. You're in a dark theater, and people are wandering

around carrying mirrors. You have a bright flashlight. Will you be able to see the

reflection from the mirrors? Probably yes. Now somebody with one of the mirrors

turns on a spotlight and points it at you. Can you bounce your flashlight off of

his mirror ? Sure, but you can never see it. You're blinded by his spotlight, and

the wimpy reflection of your flashlight from his mirror is invisible in the glare.

The problem was, he didn't just support Copernicus's idea, and he did not stick to teaching it as a theory, as the church allowed him to do. His problem was that he promoted it aggressively as the absolute truth, and that is what put him on a collision course with the Vatican. He was tried for heresy because he was held to be trying to reinterpret the Bible.

Copernicus's theory, as promoted by Galileo, was eventually replaced by Kepler's theory, but the idea of having the Sun at the center was retained. In the 18th century the discovery of the law of gravity and the laws of motion showed that Kepler's model was very close to reality, and it's the model in use today with slight modifications from relativity.

Eight if you don't count Pluto. That is - 8 major planets. But there are several minor planets though; Pluto (obviously) Ceres (in the asteroid belt) Charon (Pluto's twin planet) and several others that are farther out than Pluto. look them up online - Trans-plutonion planets or planetoids.

In order from the sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune

Asteroids, meteoroids, comets, and dust are considered part of our solar system because they orbit the Sun within its gravitational influence. They are remnants from the formation of the solar system and are composed of materials that originated from the same nebula that formed the Sun and planets. Their orbits and compositions provide valuable insights into the early history and evolution of our solar system.

Both the Lowell system and Slater's system were forms of early textile mill operations in the United States during the Industrial Revolution. They were both based on the concept of using waterpower to drive textile machinery and employed young women and children as factory workers. Additionally, both systems contributed to the growth of industrialization in the United States.

Uranus and Venus are the two planets in our solar system that rotate on a highly tilted axis. Uranus has an extreme tilt of about 98 degrees, causing it to essentially roll on its side as it orbits the Sun. Venus, on the other hand, has a tilt of about 177 degrees, which means it rotates in the opposite direction to its orbit around the Sun.

this dude stinks but the moon is a satilite to the earth

Is Uranus the coldest planet in OUR solar SYSTEM

is actually how you should write the question.

Pluto used to be the coldest planet in the solar system with an average -235 to -210 degrees Celsius!

But since Pluto was classified as a dwarf planet since 2006 it no longer counts as one of the planets in our solar system. So Uranus IS the coldest planet with -224 degrees Celsius.

No. There is only one star in our solar system. You probably call it the sun.

The solar system consists of the sun, eight planets, moons, asteroids, and comets. It is bound together by gravity, with the sun at the center. The planets revolve around the sun in elliptical orbits. Each planet has unique characteristics like size, composition, and atmosphere.

Saturn's largest moon is Titan ( known as mother of the other moons ).

The second largest is Rhea.

The five main components of the solar system are the Sun, eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), their moons, asteroids, and comets. These components all orbit around the Sun due to its gravitational pull.

Professor Filius Flitwick is the Charms Master and the head of Ravenclaw house at Hogwarts School of Witchcraft and Wizardry. He taught Harry, Ron and Hermione the spell 'Wingardium Leviosa' in Harry Potter and the Philosopher's/Sorcerer's Stone.

The source of light and heat for the eight planets in our solar system is the Sun. It emits light and heat through nuclear fusion reactions at its core, which radiate out into space and reach the planets in our solar system, allowing them to receive energy for warmth and illumination.

The region of space that contains the material of our solar system is termed the interstellar medium. This is the space between stars that is filled with gas, dust, and other debris.

The approximate orbital period of an object at a distance of 65 AU from the sun would be around 177 years. This corresponds to Kepler's third law of planetary motion, which relates the orbital period of a planet to its distance from the sun.
