The Astronomy: 97 Klotho is a fairly large main-belt asteroid. While it is an M-type, its radar albedo is too low to allow a nickel-iron composition. Klotho is similar to 21 Lutetia and 22 Kalliope in that all three are M-types of unknown composition. 13-cm radar observations of this asteroid from the Arecibo Observatory between 1980 and 1985 were used to produce a diameter estimate of 108 km. 120 Lachesis is a large main-belt asteroid. It was discovered by French astronomer Alphonse Borrelly on April 10, 1872, and independently by German-American astronomer Christian Heinrich Friedrich Peters on April 11, 1872. Photometric observations of this asteroid were made in early 2009 at the Organ Mesa Observatory in Las Cruces, New Mexico. The resulting light curve shows a synodic rotation period of 46.551 ± 0.002 hours with a brightness variation of 0.14 ± 0.02 in magnitude. It has the longest rotation period of an asteroid more than 150 km in diameter. As a primitive C-type asteroid it is probably composed of carbonaceous material. 273 Atropos is a typical Main belt asteroid that was discovered by Austrian astronomer Johann Palisa on March 8, 1888 in Vienna. Photometric observations of this asteroid at the Palmer Divide Observatory in Colorado Springs, Colorado in 2007 gave a light curve with a period of 23.852 ± 0.003 hours and a brightness variation of 0.60 ± 0.03 in magnitude.

The Mythology: Okay, so these ladies (like most of my favorite bodies to work with) are primordial, and their stories a matter of great debate. Some trace them back to the time of the Titans, some say that they were children of Zeus and Themis and at their fathers command, others say they pretty much just have always been there and Zeus is just as subject to their power as anyone else. No one really agrees on any of it. What they do agree on is their functions; Klotho is the spinner, making the thread and associated with beginnings, Lachesis is the one who measures the thread, determining how much is needed, associated with the present or the middle of the story, and Atropos is the cutter of the cord, the ending. And they would like me to impress upon you all that they are not haggard old women who only have one eye and one tooth between them. That is hurtful slander and they will not stand for it anymore!
The Astrology: Obviously these lovely ladies have similar themes astrologically as well as mythologically. The trouble with them is that it is insanely hard to see them in action, but astoundingly easy in hindsight. Of course, this lends to far more meaning in transit than in the natal chart. The pattern can only be seen when its complete, with perspective. In the chart, you must use all three of them together to see what the hell is going on- Sure, you can focus on one but it wont tell you the full story on its own. In addition to that, Martha Lang-Wescott identifies Klotho as having to do with "conditions (fate and expectations) at the beginning; initial understanding, what is apparent at the start, origins/beginnings in general." I would add to that what one is "made of," having (or not having) "the right stuff," possibly even textiles; Lachesis as signifying "intervention, assessment midway into a sequence, what 'interrupts' an evolving sequence from going as one would have expected (from the way it began or is underway)". Marianne Alexander adds what happens when something is allowed to continue without intervention; or something that occurs by default. One may also say Lachesis indicates deciding the length or duration of something, putting a stop to something (or trying to); and Martha Lang-Wescott has linked Atropos to endings, completion, conditions at the finish, what is needed to conclude. Marianne Alexander has linked Atropos to repetitive action, such as oil drilling. Atropos, I believe, can also signify cutting off, termination, pounding, percussion, "beating one's head against the wall" or "keeping on plugging away" at something.
To find out where they show up in your chart, go to astro.com, put in your birth details and in the extended options, all the way at the bottom there will be a menu of additional objects. Under that is a blank space where you can enter the number 97,120 and 273, for Klotho, Lachesis and Atropos respecitvely. Once you have those entered, generate the chart!
