The Solar System

Earth is unique in the solar system because it is the only known planet that has liquid water on its surface, which is essential for life as we know it. Additionally, Earth has a atmosphere that contains the right combination of gases to support life and moderate its temperature.

Because it is a large measurement to measure a large distance (there would be immense amoughts of zeros behind a measurement like that given in miles, yet a lightyear is much too large). It is simply the right unit to measure distances that large.

Epimtheus it is a very smallest satellite in solar system

Ganymede, one of Jupiter's moons, is the largest moon in the solar system. Third in size is Saturn's moon Titan.

To create a replica of the solar system, you will need various-sized balls (representing planets), string or wire (to hang the planets in order), paint or markers (to color the planets), a larger ball for the sun, and a base to hang the planets from. You can also add optional materials like foam balls for moons or styrofoam for asteroid belts.

Other way around - the Solar System is a part of space.

Out of an accretion disc. A disc of materials left over from the formation of a star (in this case our sun) orbiting. Small particles bump into each other and stick. Slowly over time it isn't the rigidness of the particles in that environment which causes them to stick, but at a certain size it will begin to bend space and time to where the larger chunks have significant gravity so other particles are drawn towards them. As the bigger pieces collide over time they also begin to hold together until they have what is known as hydrostatic equilibrium. This is where the object has enough gravity to hold a roughly spherical shape. Thus a planet is born. Gas planets are slightly different only in the respect that solid portions are not as visible; they fall towards the center.

The scientist who first suggested that Earth and other planets in the solar system revolve around the sun was Nicolaus Copernicus, in his work "De Revolutionibus Orbium Coelestium" (On the Revolutions of the Celestial Spheres) published in 1543.

There is a constellation called "Ursa (not "Ursula") Minor" - the little bear, or "little dipper". The tip of the "little bear's" tail is Polaris, the North Star. The rest of the stars in the Little Dipper are very faint.

a planets year is determined by how long it takes the planet to circle its sun. As a general rule the farther the planet is from its sun the longer its year will be.

Gas planets are those planets which are not made up of rocks or materials. They are composed of gases only. Eg- Jupiter

Mercury, Venus, Terra (Earth), and Mars. Yes, there are 4 inner planets. These are called the "Terran" planets.

There are several planets in the solar system that have yet to be explored extensively, including Uranus and Neptune. However, all the planets have been visited by spacecraft, with flybys and some dedicated missions to study them. Currently, there are no plans for new missions to these planets, but their moons remain interesting targets for future exploration.

Modern judicial systems are characterized by the separation of powers among the executive, legislative, and judicial branches, ensuring independence and checks and balances. They also prioritize due process, equality before the law, and transparency. In contrast, pre-modern systems often relied on hierarchical or feudal structures, with justice administered by monarchs or nobility, and limited legal protections for the accused.

According to some scientists publications the average speed of the earth rotation is about 30km/s, so 15 minutes has to be 27000km

The Sun is the largest object in our solar system, comprising about 99.8% of its total mass. By comparison, all the other objects in our solar system, including planets, moons, asteroids, and comets, make up only about 0.2% of the solar system's mass.

The first planet in our solar system that is primarily made up of heavy metals is Mercury. It has a large metallic core, predominantly made of iron and nickel, which is thought to make up about 60% of its mass.

The Caloris Basin is an impact basin. It is one of the largest impact craters in the solar system.

It was created after the heavy bombardment period and is estimated to be 3.8 billion years old.

The three theories of the formation of the solar system are the nebular theory, the planetesimal hypothesis, and the gravitational instability theory. The nebular theory proposes that the solar system formed from a rotating disk of dust and gas, while the planetesimal hypothesis suggests that small, solid bodies collided and accreted to form planets. The gravitational instability theory proposes that clumps of material in a protoplanetary disk collapsed under their gravity to form planets.

Asteroids are typically only a few metres to a few hundred metres across. The largest ones may be a few hundred km across, with the largest asteroid being a dwarf planet called Ceres (974km across.

Planets are larger than asteroids, from around 4878km across (Mercury's diameter - the smallest) to around 22,400 km in diameter (Jupiter - the largest).

The Sun is much bigger again, with a diameter of 1,392,000 km.

Pluto is the only one that has been taken away from the solar system for now but more planets are beginning to be argued over. Pluto was taken out because it was a moon.

As with all branches of the sciences, as new evidence comes to light, old ideas receive revisions or are sometimes abandoned for improved ideas. It was once thought the planets and Sun orbited the Earth; later it was realized it was more accurate to say the planets orbited the Sun since that notion was more consistent with observations.
