Planetary habitability in the Solar System

<a href="/facts/Planetary_habitability/n8A0ehR8">Planetary habitability</a> in the <a href="/facts/Solar_System/QIcLSazQ">Solar System</a> is the study that searches the possible existence of past or present <a href="/facts/Extraterrestrial_life/arxCPFTQ">extraterrestrial life</a> in those celestial bodies. As <a href="/facts/Exoplanet/zjfmqfUf">exoplanets</a> are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct <a href="/facts/Telescope/BDwYahhR">telescope</a> observation, <a href="/facts/Space_probe/AeWRBITP">space probes</a>, <a href="/facts/Rover_(space_exploration)/Qo7y32Cz">rovers</a> and even <a href="/facts/Human_spaceflight/VgVxsGmq">human spaceflight</a>.
Aside from Earth, no planets in the solar system are known to harbor life. <a href="/facts/Mars/AQGtVvz0">Mars</a>, <a href="/facts/Europa_(moon)/2A9nleK3">Europa</a>, and <a href="/facts/Titan_(moon)/lg0l9PCH">Titan</a> are considered to have once had or currently have conditions permitting the existence of life. Multiple rovers have been sent to Mars, while <a href="/facts/Europa_Clipper/LuaX203A">Europa Clipper</a> is planned to reach Europa in 2030, and the <a href="/facts/Dragonfly_(Titan_space_probe)/D753heTr">Dragonfly space probe</a> is planned to launch in 2027.
