<p style="margin:0in0in0pt;text-align:justify" class="MsoNormal"><font face="Times New Roman" size="3">How are astronomers seeking planets with liquid water? The reason I ask is because as I understand it, our solar system is unique. Most planets in our solar system have fairly circular orbits around the sun. (As opposed to <u>very</u> elliptical orbits) Obviously, planets with very elliptical orbits probably do not remain temperate enough to either keep water between 0-100C. That being said, I would imagine planets with very large ellipses would have trouble keeping water (in any form) on the planet surface all together. </font></p><font face="Times New Roman" size="3"> </font> <p style="margin:0in0in0pt;text-align:justify" class="MsoNormal"><font size="3"><font face="Times New Roman"><span> </span>So my question becomes, would a good starting point for discovery of water on other planets be to first identify planets with a more circular orbit around its star? (or even moons of other planets for water in any form) Thanks.</font></font></p><font face="Times New Roman" size="3"> </font> <p style="margin:0in0in0pt;text-align:justify" class="MsoNormal"><font face="Times New Roman" size="3">(apologize if that is what astronomers are doing already)</font></p>
