El descubrimiento de Brahe que la coma o cabellera del cometa apuntaba lejos del sol era también significativo.

One failing Brahe had in his measurements was in exactly how far out of the atmosphere the comet was, and he was unable to supply meaningful figures for this distance;<ref name="Gal" /> however, he was, at least, successful in proving that the comet was beyond the orbit of the moon about the Earth,<ref name="hist">Grant, p.305</ref> and, further to this, was probably around three times further away.<ref>Seargent, p.107</ref> He did this by comparing the position of the comet in the night sky where he observed it ([[Hveen]] near [[Copenhagen]]) with the position observed by an unknown astronomer in [[Prague]] at the same time, giving deliberate consideration to the movement of the Moon. It was discovered that, while the comet was in approximately the same place for both of them, the Moon was not, and this meant that the comet was much further out.<ref>Lang, p.240</ref>
 
El defecto en las medidas de Brahe, estaba en no saber exactamente que tan lejos fuera de la atmósfera estaba el cometa, y él era incapaz de suministrar cifras significativas para esta distancia; sin embargo, al menos estaba acertado en la confirmación que el cometa estaba fuera de la órbita de la luna sobre la Tierra, y con relación a esto, calculó que estaba probablemente alrededor de tres veces más lejos. Él hizo esto comparando la posición del cometa en el cielo de la noche donde él lo observó en ([[Hveen]] cerca [[Copenhague]]) con la posición observada, al mismo tiempo, por un astrónomo desconocido en [[Praga]], dando la debida consideración al movimiento de la Luna. Descubrió que, mientras el cometa estaba en aproximadamente el mismo lugar para ambos, la Luna no, y esto quería decir que el cometa estaba mucho más lejos.
Brahe's finding that comets were heavenly objects, while widely accepted, was the cause of a great deal of debate up until and during the seventeenth century, with many theories circulating within the astronomical community. [[Galileo]] claimed that comets were optical [[phenomena]], and that this made their [[parallax]]es impossible to measure. However, his hypothesis was not widely accepted.<ref name="Gal">{{Cite web|url=http://galileo.rice.edu/sci/observations/comets.html|title=The Galileo Project|accessdate=25 March 2007}}</ref>
Brahe consideraba que los cometas eran objetos divinos, algo extensamente aceptado en la época, aunque esto fue la causa de muchos debates hasta el decimoséptimo siglo, con muchas teorías que se circulaban dentro de la comunidad astronómica. [[Galileo]] mismo afirmó que los cometas eran [[fenómenos]] ópticos, y que su [[paralaje]] era imposible de medir. Sin embargo, su hipótesis no fue aceptada extensamente.

Four other observers of the comet — [[Helisaeus Roeslin]]; [[William IV, Landgrave of Hesse-Kassel]]; [[Cornelius Gemma]]; and [[Michael Mästlin]] — also identified it as superlunary. The most complex of the early representations of the comet, described as "an interesting, though crude, attempt," may have been that of Roeslin.<ref>Robert S. Westman, "The Comet and the Cosmos: Kepler, Mästlin, and the Copernican Hypothesis," in ''The Reception of Copernicus' Heliocentric Theory: Proceedings of a Symposium Organized by the Nicolas Copernicus Committee of the International Union of the History and Philosophy of Science, Torun, Poland, 1973'' (Springer, 1973), pp. 10 and 28.

The [[literature]] resulting from the passing of the comet was prolific, and these works, as well as the ideas presented by many astronomers, caused much controversy. However, the idea that comets were heavenly objects became a respected theory, and many took this concept to be true.<ref name="Gal" />
