A planet (though I doubt it would actually be one) with a mass of 450 kg would have a mass of 450 kg (obviously). The phrase "450kg stellar mass" is meaningless.
The repeating pattern of the stellar motion reveals the presence of a planet orbiting the star. By analyzing the variations in the star's radial velocity, astronomers can determine the planet's mass, orbital period, and distance from the star. This information helps to characterize the planet and understand its orbit within the stellar system.

A black hole is the stellar remains of a massive star.

In their mass. a "stellar black hole" has a few solar masses (a few times the mass of our Sun), while a supermassive black hole (found in the center of most galaxies) typically has a mass of millions or billions times the mass of our Sun.
Density of a planet = (Planet's mass) divided by (Planet's volume)
Venus is the planet closest in mass to Earth, with a mass about 81% that of Earth.
Potential evidence for an extrasolar planet includes observing a star's wobble due to the gravitational pull of an orbiting planet, detecting a dip in a star's brightness as a planet passes in front of it (transit method), or directly imaging a planet near a star using advanced telescopic techniques.
Yes, a planet cannot become a star through stellar evolution. Stars are formed from collapsing clouds of gas and dust, while planets are formed from the leftover material in a star's protoplanetary disk.
The mass of planet Earth is 5.9736 × 1024 kg
The endpoints of stellar evolution are: White Dwarf Neutron Star Black Hole The endpoint is dependent upon birth mass of the star.
