Give an easy definition for protoplanets?
A precursor to a planet. You could also call it an early stage in the formation of planets.
If you don't do anything to change your life, that's fate.
If you do something to change your life, that's destiny.
Who created the modern model of the solar system by discovering that the planets move in ellipses?
Johannes Kepler whose new theory was published in 1609.
What is one chacteristics of Jupiter that makes it easily recognized?
Jupiter is most easily recognized by its colorful bands of clouds and the Great Red Spot, an enormous storm that has ranged for at least 300 years.
How long does Saturn take to rotate in relationship to earth?
It takes Saturn about 10.7 Earth hours to make one full rotation around its axis.
How many moons do mercury venus earth and mars have?
Mercury 0
Venus 0
Earth: 1 Moon (luna)
Mars: 2 (Deimos, Phobos)

What does it mean when the first four planets are terrestrial planets?
It means that they are somewhat similar to Earth. Note that the outer planets are gas giants, which means that:1) They are much larger than Earth, and
2) They don't have a surface where you can stand on - they are basically just gas - though it is believed they have some solid core, deep inside.
Why do all countries not experience day at the same time?
The sun can shine on only half of the world at a time.
Inner Engineering is a comprehensive program offered by the Isha Foundation, designed to promote personal development and well-being through a combination of yoga, meditation, and self-awareness practices. It aims to help individuals achieve mental clarity, emotional balance, and physical health by fostering a deeper understanding of themselves and their connection to the world. Participants learn techniques to enhance their inner experience and cultivate a sense of inner peace and joy. The program is suitable for people of all backgrounds and is often seen as a foundation for more advanced yogic practices.
On a clear day how many kilometres can you see up to?
the earth curves about eight inches in a mile. So, if the land is completely flat (or if you are on water) and your eyes are six feet (72 inches)above the ground, you can see for 72/8 = 9 miles. the higher you go - on a tower or the mast of a ship, say - the farther you can see.
No hardware sent to Mars has ever been returned to Earth, and nothing
that's landed on the Martian surface has ever been launched from it.
"Volatile" material means stuff that is gaseous at "room" temperature. As close to the Sun as the Earth is, anything inside the Earth's orbit - and most stuff inside Mars' orbit - will already have been vaporized. Once it is gaseous and in space, the solar wind will carry it away into the outer solar system.
Once out past the orbits of Jupiter or Saturn, most gasses like ammonia or carbon dioxide will condense or freeze, and if it comes close to any larger body, it will probably stick to it as frost.
How large is the little dipper as compared to other parts of the solar system?
The 'little dipper', or the constellation of Ursa Minor, the little bear, is not part of the solar system. It consists of stars, like our Sun, which are much further away than any planet, even Pluto. Polaris, the brightest star in the constellation, is 434 light years away. Kochab, the second brightest star is 131 light years away. They, and the other stars of the group, have nothing to do with each other, they just happen to be in the same rough direction as seen from Earth.
Where are small icy bodies loacted?
Small icy bodies are located in the solar system where they orbit the sun.
What is Mercury's surface temperature?
Mercury's surface temperature varies greatly depending on its location on the planet. It can range from about 800 degrees Fahrenheit (430 degrees Celsius) on the side facing the Sun to -290 degrees Fahrenheit (-180 degrees Celsius) on the side facing away from the Sun.
Earth's atmosphere stops smaller meteors from reaching the surface, but not large ones. The real reason Earth has few impact craters is because it has many active geologic processes. Erosion, sedimentation, volcanic eruptions, and plate tectonics are constantly renewing and changing Earth's surface. Very little of Earth's crust remains from the time of the Late Heavy Bombardment, and most that does remain has been heavily altered. By contrast the moon is, for the most part, geologically dead. Asteroid and comet impacts have been the only significant changes since the moon formed. Therefore craters on the moon have remained mostly unchanged for billions of years.
As you move further out into the solar system, the amount of solar energy that planets receive decreases. This is because the intensity of sunlight weakens with distance due to the inverse square law. Planets like Pluto receive significantly less solar energy than planets closer to the sun, impacting their surface conditions and climates.
What body in the solar system is stationary?
For the purposes of modelling the Sun is assumed stationary, but we know the Sun is going round the galaxy at a good speed, so everything is on the move all the time.
What was made first in the solar system?
We believe that the solar system formed from an enormous cloud of dust (blown into space by the supernova explosions of dying stars) and gas (some original hydrogen that had been floating around in space since the "Big Bang", and some gas from those exploding stars). So the solar nebula (that's the name for the cloud of gas and dust) was even before the solar system became "solar".
We suspect that some external shock wave (probably one of those supernova explosions) triggered the gravitational collapse of the gas cloud. When enough gas had fallen to the center, it generated enough heat and pressure to form a star. So the star was the first thing in the "solar" system.
