Scientists think planets, including the ones in our solar system, likely start off as grains of dust smaller than the width of a human hair. They emerge from the giant, donut-shaped disk of gas and dust that circles young stars. Gravity and other forces cause material within the disk to collide.
What planet formed first in our solar system
Jupiter and Saturn are thought to have formed first and quickly within the first 10 million years of the solar system. In the warmer parts of the disk, closer to the star, rocky planets begin to form. After the icy giants form there’s not a lot of gas left for the terrestrial planets to accrete.

When was the planet first formed
NASA’s Hubble Space Telescope precisely measured the mass of the oldest known planet in our Milky Way galaxy. At an estimated age of 13 billion years, the planet is more than twice as old as Earth’s 4.5 billion years. It’s about as old as a planet can be
Can we see a planet moving
The motion of the more distant planets against the stars can be seen with the naked eye over longer periods of time, although a pair of binoculars will help to reveal their motion over a much shorter time span
What is the movement of planets through sky
Typically the superior planets move against the background stars from west to east, this is called prograde motion. However at times they undergo retrograde motion as viewed against the background stars, moving east to west. This is a result of the faster Earth passing the slower planet at opposition.
How can I see earth moving
As others have pointed out, you can “see” the spinning of the Earth by watching the stars rotate around a point close to the North Star. The spinning of the Earth also reduces the amount you weigh when you travel to the Equator, due to the centrifugal force of the spin
Scientists think that CO is necessary for planet formation, and finding it and understanding it in a young protoplanetary disk is important.
Each planet that forms is distinct from others. And each one is a chance for life. Not only to appear and then languish in the mud and muck for a couple of billion years, but to eventually evolve complexity. That’s how we got here
How was earth formed
The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon.

Fascinating insights into planet formation and celestial motion. It’s incredible to think of our solar system’s history and the ongoing mysteries of space. The formation of Earth and the moon is a remarkable story of cosmic events. And, while we ponder the cosmos, let’s not forget to seize those ‘steal deals’ right here on Earth. Thanks for sharing this intriguing piece!

Good post. I have many questions and my own theories about the moon. Still researching.
I think moon was used as fueling station or place stop before landing on the earth by the ancient aliens who built structures like pyramids and great impossible structures. One of my theories is that the moon was built by aliens not naturally formed. yea, I’m crazy 😊

May be you are right but we are there on moon now and in future if it is true , we will come to know
