I believe it is because scientists have not discovered a way to make telescopes able to magnify to that extent.
Saturn has three main rings. You need a telescope, but they are visible in a small telescope.
The planet you are referring to is likely Kepler-452b, which is located about 1,400 light-years away from Earth. It was discovered by NASA's Kepler Space Telescope and is considered a "cousin" to Earth due to its potential habitability.
No, Earth is a planet orbiting the Sun.
Any telescope that you own, or can borrow, or rent, or on which you can be assigned time for your research.
No
No Earth-like planets have been discovered yet, but our best telescopes are (so far!) incapable of locating any extra-solar planets that small. With the launch of the James Webb Space Telescope, this may change.
You can see Venus or other planets through a telescope from anywhere on Earth. The visibility of the planets depends on their current position in relation to Earth and the time of year. It is best to observe them from locations with minimal light pollution for optimal viewing.
Earth or any planet where life is possible
Yes, they have discovered 1 more planet. Apparently, they have found a planet by telescope, which is 40% water and 60% earth, it has 3 orbited moons and 2 suns. they are planning on visiting this planet in 2013, when they are 100% sure it is safe.
I suggest you check your question. Earth is a planet. Earth does not 'contain' any planets; therefore the only answer to your question is....earth.
The moon is Earth's natural satellite and is not next to any other planet in our solar system. It orbits around Earth.
