It has only been a few years since the first solar system apart from ours was detected, and they are still extremely difficult to study, so this whole subject is still in its infancy. PHOTO: This brings the total number of confirmed exoplanets to 4,073. Whether this estimate is correct and how similar other solar systems are to ours, remain to be seen. Francis Reddy/NASA's Goddard Space Flight Center. Faint red Proxima Centauri is nearly a fifth of a light year from Alpha Centauri A and B. The planet orbits an orange, K-type star that is cooler and dimmer than our Sun and is located about 1,000 light-years from Earth in the constellation Lyra. Stars don’t remain completely still when they are orbited by planets; they move in small circles as a response to the pull of gravity from the planets. It shows how "puffy" a ringed planet may look to us from afar. The planet weighs about 6.6 times the mass of Earth and is shown passing in front of LHS 1140. A Warner Media Company. Two of them have the potential to support life. Depicted in blue is the atmosphere the planet may have retained. European Southern Observatory/ESO/L. This makes it the closest solar system to Earth that contains multiple planets. Has there been any black holes in our solar system and if so what damage have they caused. NASA discovers entire solar system that is 'remarkably similar' to ours The system could help us learn how our own planets were formed. Our solar system is just one specific planetary system—a star with planets orbiting around it. P Rubini/AM Lagrange. Outside of our Sun, our system's nearest neighbor is Alpha Centauri. M. Weiss/European Southern Observatory/CfA. This is an artist's illustration of the Kepler-88 planetary system, where one giant exoplanet and two smaller planets orbit the Kepler-88 star.

Space Exploration To see a some interesting solar system maps including "Space without the Space" and "If the moon were only 1 pixel", visit our Solar System Maps page. Harvard-Smithsonian, Center for Astrophysics/D. Scientists have captured the first direct image of a solar system that closely resembles our own. Scientists say that the solar system around the star Epsilon Eridani looks really similar to the one around our own sun. The Sun is some 333,400 times more massive than Earth and contains 99.86 percent of the mass of the entire solar system. The star at the center of the nearby system, called Epsilon Eridani, is a younger, slightly cooler and fainter version of the sun. The star, named Epsilon Eridani, is a similar size to the sun, though much younger, and as the closest planetary system that is similar to ours it is in a prime spot for research.
