Yes &#8212; one such system is Kepler-90. Cataloged by the Kepler satellite that operated from Earth orbit between 2009 and 2018, eight planets were discovered, giving Kepler-90 the same number of known planets as our Solar System. Similarities between Kepler-90 and our system include a G-type star comparable to our Sun, rocky planets comparable to our Earth, and large planets comparable in size to Jupiter and Saturn. Differences include that all of the known Kepler-90 planets orbit relatively close in &#8212; closer than Earth&#8217;s orbit around the Sun &#8212; making them possibly too hot to harbor life. However, observations over longer time periods may discover cooler planets further out. Kepler-90 lies about 2,500 light years away, and at magnitude 14 is visible with a medium-sized telescope toward the constellation of the Dragon (Draco). The exoplanet-finding mission TESS was launched in 2018, while missions with exoplanet finding capability planned for launch in the next decade include NASA&#8217;s JWST and WFIRST. via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap200428.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Do other stars have planetary systems like our own?
