Planetary Science

Earth is mostly made up of iron, oxygen, silicon, magnesium, sulfur, nickel, and other elements. The crust is largely composed of silicon and oxygen in the form of silicate minerals, while the core is primarily made of iron and nickel.

If you want to change the number of rings you're wearing, whether it's rings on your finger, earrings, or some other type of rings, the process is simple. All you must do is take off or put on more rings.

It's Newton's first law of motion: "An oject in motion will stay in motion (with the same velocity) until an outside force acts upon it and an object at rest will stay at rest until an outside force acts upon it."

Scientists suspect that of the well known planets that Jupiter has a solid core that is large in size. It has been discovered that Jupiter contains a core that includes rock and hydrogen metals, but scientists are unsure if deep within the planet contains a true solid core. Of all the nine planets, Jupiter's core contains the most "solid" case for a true solid core.

Galileo Galilei introduced a new scientific idea that the Earth revolves around the Sun. Before this, Aristotle, a Greek philosopher have said that the earth was at the center and the sun revolves around it. When the physicist Galileo presented his idea, the people in the Church was against it as Aristotle's ideas was already stated in the Divine Book (The Bible) during that time.

No because there is water on the planet too. Also the animals that are on the planet aren't rocks either.

Living on Mars in the near future is a possibility, but there are many challenges that need to be addressed first, such as developing advanced life support systems, ensuring sustainable food and water sources, and protecting against harsh radiation. Organizations like NASA and SpaceX are actively working towards making human settlement on Mars a reality, but it will likely be several decades before it becomes a practical and safe option for long-term habitation.

Earth is the only planet that people have ever walked on.

The only other body away from Earth that people ever walked on is the Moon, and

that has not happened in over 40 years.

The nearest planet (Venus) is always more than 100 times farther away than the Moon is.

Venus is hot enough to melt spacecraft and cook people, so even if it were possible, we

would not send people to land on it.

The next nearest planet (Mars) is always more than 140 times farther away than the Moon is.

I would say it is a 180. on a clock if the hand is on 12 half a turn would be six. a full turn is 360,so half is 180....i think thats what you mean.

The average distance between Earth and the Moon is about 384,400 kilometers (238,855 miles). This distance can vary slightly due to the elliptical nature of the Moon's orbit around Earth.

No I am a astronot Iwent past the Milkyway and didn't see a single planet but I saw a whole new world!

A planet's orbital radius directly affects its orbital period through Kepler's third law of planetary motion. The farther a planet is from the star it orbits, the longer its orbital period will be, assuming all other factors remain constant. This relationship is expressed mathematically as T^2 ∝ r^3, where T is the orbital period and r is the orbital radius.

The Moon rotates at the same rate it revolves, so the same side always faces Earth, because the Moon is tidally locked to the Earth. While it does spin on its axis, it takes the same amount of time for one complete turn as it does to circle the planet (about 27.32 days).

When the Moon was first formed it rotated faster than it does now. But because it is smaller than the Earth and its weight unevenly distributed, the tidal friction between the Earth and Moon gradually slowed it down. This works the other way too: the Moon is slowing Earth's spin, and as it does, it moves out further from the Earth. The eventual end state would be for the Earth and Moon to always face each other. This would require billions of years, and will likely first be interrupted by other events in the solar system.

Astronomers estimate the moon probably became tidally locked more than a billion years ago.

There are four main planets in "Ratchet: Deadlocked": Catacrom Four, Sarathos, Kronos, and Shaar. Each planet offers different challenges and enemies for Ratchet and his team to conquer.

The planets are not all the same distance from the Sun, which determines how far they have to travel, and how fast they are moving. Planets farther from the Sun have much longer orbits and are not moving as quickly. So their period of revolution (year) is longer.

It depends on the mass of the moon and the relation of it's proximity to the planet it is orbiting. Since humans have only traveled to the Earth's moon, we can only truly get an understanding by being there. However, we do have an idea of how strong or weak gravity is on each moon. More than likely, the moon with the weakest gravity is most likely Mars' two moons, which aren't really moons, rather old asteroids orbiting the red planet. Phobos and Deimos. The two moons with the strongest gravity are most likely Titan (The only known moon in the solar system with a thick atmosphere) and Triton (One of Neptune's moons).

Now for the planets:

The planet with the weakest gravity is most likely Mars. The atmosphere is extremely thin and the planet is bitterly cold. Now, the planets that receive the strongest gravity award are the gas giants. All gas giants (Jupiter; Saturn; Uranus; Neptune) would literally crush you into nothing the gravity is so strong. These planets are also the deadliest and most uninhabitable. But, to sum everything up, there is no clear cut 'one to three' lineup. The solar system is still very mysterious and holds secrets scientists still have to uncover. Hope this helps and answers your question.

Gas planets are typically made up of volatile gases and do not have solid surfaces, so they cannot "blow up" in the traditional sense. However, extreme events such as intense gas pressure, gravitational disruptions or collisions with other celestial bodies could disrupt a gas planet's structure or cause it to break apart.

Gravity is the force that keeps planets and moons in orbit. The gravitational pull between the planet or moon and the object they are orbiting around, typically a star like the sun, is what keeps them moving in a stable path. This balance between the gravitational force and the object's inertia causes them to continuously orbit in a closed path.

The moon orbits the Earth, which takes one year to go around the Sun.

Planets orbit around the sun due to gravitational attraction. The sun's gravitational pull keeps the planets in their orbits, while the planets also exert a gravitational force on the sun, causing it to wobble slightly. The sun provides the heat and light necessary for the planets to sustain life.

The planet "Mercury" is the first planet in our solar system. It is the closest to the sun. Usually Mercury is almost impossible to see because the Sun's glare blinds us to it. It is 57.9 Million Kilometers from the sun with a surface temp ranging between -180 to +430 Celsius. It takes 87.97 Days to orbit the sun and it has no moons.

The Earth is 3.64 times larger than Moon's Circumference. (Earth's Circumference) 39,843 divide by (Moon's Circumference) 10,921=3.64

Gravity ! The earth is being constantly pulled towards the sun, by the sun's gravitational pull. At the same time, centrifugal force is trying to 'throw' the earth out into space. The two forces just about cancel each other out - resulting in the earth remaining in orbit around the sun.

To orbit around Earth, the centripetal force of the object must equal the gravitational force. Therefore: mv2/r = GMm/r2 v2 = GM/r v = sqrt(GM/r) Plug in G: universal gravitational constant (6.67*10-11 Nm2/kg2), M: mass of Earth (5.97*1024 kg), and r: radius of orbit as measured from Earth's centre (e.g. 1000 km above the ground would correspond to an r of 1000 km + radius of the Earth (6367.5 km = 7367.5 km = 7367500 m)
