These discoveries have just been confirmed — within the week, i.e., August 2, 2020.
Two, i.e., P/2020 O1 & P/2020 O3, are periodicals — in that they have orbital periods that are less than 200-years. Actually both of these have comparatively short orbital periods, i.e., 4.3 & 10 years. That also means that they don’t go very far from the Sun (or us). Also interesting that both these were discovered right after their most recent perihelions. Their next ones are way out.
Not so with the non-periodic, i.e., C/2020 O2. It is due to perihelion a year from now. Its orbital period has yet to be established. But, note its eccentricity. It is over ‘1’. Anything 1 or over has HIGH eccentricity by definition.
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.
