Hy.
What are the others known solar systems ?
Thanks!

russ_watters said:Anyway, this article implies that that is the only such photo yet taken and it is only possible because the planet is large and orbiting a brown dwarf at a large distance and both are imaged in infrared. A very unusual case. http://www.eso.org/public/news/eso0511/

If history is any guide a small proportion of people will move there and then spend large amounts of time, money and effort keeping those other aliens outFawkesCa said:if a habital planet is ever found, each and every human on Earth will demand vacations there and ALL research will be directed toward reaching it... I PROMISE YOU THAT

Other solar systems, also known as extrasolar systems, are systems consisting of a star or stars, along with any planets, moons, asteroids, and other celestial bodies that orbit around it. These systems are similar to our own solar system, but can have different compositions, sizes, and number of planets.
Other solar systems are typically discovered using a variety of methods, including the radial velocity method, transit method, direct imaging, and astrometry. These methods involve observing the motion, brightness, and position of stars and their surroundings to infer the presence of planets and other objects.
The characteristics of other solar systems can vary greatly, as each system is unique. However, some common characteristics include a central star, multiple planets of varying sizes and compositions, and debris disks or belts where smaller objects like asteroids and comets can be found. Some systems may also have binary or multiple stars.
While no confirmed cases have been found yet, it is possible that other solar systems could support life. Scientists look for planets that are within the habitable zone of their star, where temperatures are suitable for liquid water to exist. They also look for other factors such as the presence of an atmosphere and potential for the planet to have a stable climate.
Other solar systems provide a wider range of data and examples for scientists to study and compare to our own solar system. By learning about the diversity of other systems, we can gain a better understanding of the formation, evolution, and potential future of our own solar system. This knowledge can also help us refine our theories and models about the universe and its origins.
