I think of the word terrestrial as referring specifically to the earth. But in the context of your question I think you are referring to a rocky planet as opposed to a gas giant. Venus is a rocky planet, or terrestrial to use your term. There are 4 rocky planets: Mercury, Venus, Earth and Mars. Don't let the water on the Earth confuse you with the term rocky. The water is extremely shallow in astronomical dimensions. The gas planets, often called gas giants, are Jupiter, Saturn, Uranus, and Neptune. Pluto is no longer considered a planet and I do not know which category it would fall into.
To find an Earth-like planet around another star, scientists search for planets that orbit in the "habitable zone" where conditions are just right for liquid water to exist on the surface. They use telescopes to detect the planet's size, orbit, and composition, looking for similarities to Earth such as a rocky surface and the presence of water. Host stars are also studied to determine if they are similar to our Sun in age, size, and composition.

small, dense, and rocky
I don't know what "captured asteroid" means in this sense (though I can't imagine any scenario in which it might conceivably be applied to Pluto). The opinion of the International Astronomical Union is that Pluto is not a planet, because it has not "cleared its orbit". That's not a "hypothesis", it's a fact.
Average density of the planet
They use spectroscopy.
A terrestrial planet is a rocky planet similar to Earth, with a solid surface and typically a thin atmosphere.

When heated by the air, dry ice reverts to a gaseous state as carbon dioxide. Some lower layers of Jupiter's gaseous atmosphere are much denser than water. He had a tendency to become gaseous after eating beans.
you ask a scientist.
There are some very rocky mountains in the west of Ireland. The Rocky Mountains are a range of mountains in the west of the USA.
