We don't know about any other other place, besides Earth, that harbors life. But many scientists think that there is life on other planets.
No (except for trace amounts). Oxygen is chemically active - without plant life continuously forming new oxygen there wouldn't be any on Earth either.
No, humans have not landed on any planets besides Earth. The main reason is the extreme distances and conditions of other planets in our solar system, such as harsh temperatures, lack of breathable atmosphere, and intense radiation. Sending manned missions to other planets would require significant advancements in technology and resources.
No. Most planets have storms of one sort or another. One of the most famous storms is the Great Red Spot on Jupiter. It's basically a hurricane that's about three times the size of Earth and has been going on for at least a few hundred years. Another example is Saturn, whose storms have the most powerful lightning strikes of any planet in the solar system.
All of the planets in orbit around our sun are much, much closer than ANY star besides our own sun.
Earth has no planets of its own. It is one and has one moon.
Yes. They don't have actual magnets, but they do have "magnetic fields". Other planets with magnetic fields are Mercury, Jupiter, Saturn, Uranus and Neptune.
some weather occurs on mars when dust blows in the surface for brief intervals so yes mars has some dust storms
Astronomers have found Earth-sized planets in other solar systems.
Earth doesn't have any planets, it isn't a star.
Since no one from Earth has visited another planet, and we have no indication that there is anyone on the other planets, Earth does not help other planets in any way. Why do you think there is something Earth does to help them- whoever them is.
Yes, Earth
