I will defer to you on the difference in docket and hearing as I am not versed in the difference, I was basically using another thread:

“Update (1515ET): Just twelve hours after it was filed, the US Supreme Court has officially put Texas’s lawsuit against Georgia, Michigan, Pennsylvania and Wisconsin on the docket, meaning the case will be heard.”
It's been going around all evening. But fortunately it's fake news.
Issues get to the Supreme Court in one of two ways. They are either appeals of lower court rulings, and the justices vote on whether or not to hear them, or the are cases where the Supreme Court is the first court to hear them, and the jurisdiction in those cases is outlined in Article III, Section 2. In the Texas case there was never any question as to whether the Supreme Court would accept the case. But there are no guarantees from here. The Supreme Court has requested responses from the defendants by tomorrow and once they review that then the will either schedule formal arguments from both sides or they will dismiss the case out of hand. If it's dismissed then it's dead. If the court scheduled oral arguments then what happens depends on how well Texas makes their case. None of this is a done deal.
Docketing means for a hearing.
