Here is the Wikipedia entry.


The official Minor Planet Center (MPC) data for the comet she discovered: C/1847 T1.

So it perihelioned, i.e., went around the Sun (at its closest) on November 14, 1847, three weeks after it was discovered on October 26, 1847. Not like today when we can spot comets 18 months away.

Note the eccentricity. Just over 1! That is significant. That means that it was on an escape orbital path — meaning that it could leave the solar system. But, we now know that eccentricity can fall, i.e., drop below ‘1’, once a comet like this gets further out into space, i.e., beyond Jupiter. Check out my comet books.


She is NOT the first woman to discover a comet. This is from my ‘Comets: 101 Facts & Trivia‘ book.
