There seems to be a misunderstanding. "Lota Cancri" is not a recognized star name. It's possible you're referring to a different star or a misspelling.

To find the distance of a star from Earth in light-years, you'll need its proper name. For example:

* Proxima Centauri: 4.24 light-years

* Sirius: 8.6 light-years

* Vega: 25 light-years

Please provide the correct name of the star you're interested in, and I can help you find its distance in light-years.
