15th Anniversery of discovery of first Kuiper Belt object

[MeteorWayne]

It's really rather amazing, when you think that 15 years ago, nothing beyond Pluto had been seen in the outer solar system, yet now there are thousands of such objects.<br /><br />We sure live in an amazing time!!<br /><br /> link <br /><br /><br /><br />1992 QB1 - First Object Discovered in Kuiper Belt <br /> From IAU Circular No. 5611 (1992 September 14) <br /><br />1992 QB1 <br /><br />D. Jewitt, University of Hawaii; and J. Luu, University of California at Berkeley, report the discovery of a very faint object with very slow (3"/hour) retrograde near- opposition motion, detected in CCD images obtained with the University of Hawaii's 2.2-m telescope at Mauna Kea. The object appears stellar in 0".8 seeing, with an apparent Mould magnitude R = 22.8 +/- 0.2 measured in a 1".5-radius aperture and a broadband color index V-R = +0.7 +/- 0.2<br /><br />1992 UT R.A.

MW,<br />Fully agree.<br />I cannot wait until Brown et al. announce the other tens of large TNO they have in their basket.

Well, Pluto is more technically a Plutino, an object in 2:3 resonance with Neptune.<br /><br />The classic Kuiper Belt is objects somewhat further out that are not trapped in that resonance.<br />It's a matter of some semantic debate, which is why I did not include it.<br /><br />The Kuiper belt definition, like that of planets/dwarf planets, etc is still a bit fuzzy until 15 years from now when we have discovered tens or hundreds of thousands of such objects beyond Neptune, and can truly have a feel for what is out there.<br /><br />So neither of us is wrong or right <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Fifteen Years already???<br /><br />Of course 1992 QB1.<br /><br />Time flies when one is having fun.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world. It was extremely large with respect to the overall size of Io and crescent shaped. It seemed unbelievable that something that big had not been visible before".</font> <em><strong><font color="#000000">Linda Morabito </font></strong><font color="#800000">on discovering that the Jupiter moon Io was volcanically active.
