Other solar systems are extremely distant from us, and are correspondingly difficult to view in detail. We are constantly devising new and more powerful telescopes, and new astronomical observation methods, with which to see what we have not previously seen.
Of course! Where we are now in space science is only the tip of the iceberg. There are so many unknown things out there.AdditionallyAstronomers are just discovering new planets outside our solar system. Until recently the planets were too far away and too dim to be seen by our best telescopes.
Saturn, Jupiter, Uranus, and Neptune are the four planets in our solar system known to have rings. Saturn's rings are the most prominent and well-known, but the other planets have less visible ring systems.
Yes. To date scientists have discovered well over a thousand planets orbiting other stars. It is believe that a large portion of the stars in the night sky have planets.
Countries do not discover planets, people do. Of the planets that aren't visible with the naked eye, the discoverers lived in England (Uranus) and Germany (Neptune), and the USA if we count Pluto.
It is likely that more exoplanets will be discovered in the future, as advancements in technology and techniques continue to improve our ability to detect them. The discovery of new planets will provide valuable insights into the diversity of planetary systems in our galaxy.
Go to Wikipedia and search the article "Extrasolar planets". It has links to several lists of planets and planetary systems.
All the planets in our solar system orbit our sun. Recently other suns, far out in Space, have been discovered to have their own planets.
Yes. As of December 12, 2013 nearly 800 systems have been discovered with planets, including more than 170 with multiple planets.
Yes, there was recently discovered forms of ancient life on mars that looked like dinosaurs
There is no maximum number, and "nebular theory" has been knocked for a loop by the recent discoveries of 400+ "extra-solar planets" - planets orbiting other stars. Classical theories predicted that planetary systems would be rare; however, it seems that every nearby star we've looked at recently has been discovered to have planets - LOTS of planets.
Not in our solar system. In fact the scientific community recently reduced the number of planets in our solar system by reclassifying Pluto as a Dwarf Planet. As for other solar systems, yes, there are still new planets being discovered; Often enough that the discoveries don't even usually rate any mention in mainstream news media.
There is no planet named Kepler. Kepler is the name of a space telescope used to find planets in other solar systems. Planets discovered with this method are given designations such as Kepler 22-b. Some planets discovered have been larger than Jupiter.
Ceres and Eris are not planets; they are classified as dwarf planets. Eris was discovered in our solar system recently and not by the Kepler mission. Ceres is not "new" either; it was discovered the first day of the 19th. Century. I didn't check the specific "Kepler-" codes, but that looks like planets discovered by the Kepler mission to be orbiting around other stars.

We do not know. Although we have detected planets in other solar systems, we do not know what colors they are.
Actually, we don't know for sure that other systems don't have as many dwarf planets. Even with the acceleration of advances in telescope technology, spotting other solar systems is not easy, and the pictures are seldom definitive. Aside from that, our system is an unusual one in many ways besides the apparently extraordinary number of planets. There are many theories about why that might be, ranging from age to chance. Perhaps the most satisfactory answer that can be given at this time is that our system is in a location that allows it to collect mass more rapidly than other systems.
Planets outside our solar system are called exoplanets. Thousands of exoplanets have been discovered orbiting other stars in the Milky Way galaxy. They come in a variety of sizes and compositions, and many are quite different from the planets in our own solar system.
