However, since the true mass is not known, it may be more massive, but not likely much.

Therefore, the true mass of the planet may be much greater than this lower limit.

The giant tree above must be but a tiny fraction of the plant's true mass.

This planet may actually be a brown dwarf if a true mass is over 13 times that of Jupiter.

As a result, the planet's true mass will be higher than expected.

The true mass of this planet will probably be much greater.

Depending on the inclination of its orbit, the true mass could be above this limit.

That is why we cannot even estimate its true mass.

When both methods are used in combination, then the planet's true mass can be estimated.

And true mass is the one thing it lacks.
