Venus is also a terrestrial. It has a diameter of 3,959 miles, 6,371 km. It's hotter than Mercury even though it's the second closest to the sun. It takes 243 Earth days for one day on Venus and 225 days for a year. It has no moons nor rings.
Mars is a terrestrial planet. It has a diameter of 4,212 miles, 6,779 km. It has lost atmospheres and water over the years and the believe that it could have been a planet to live on at one point in time. it takes 687 earth days for it to be one year on mars and a little over a earth day for one day on Mars. It has 2 moons and no rings.

A meteoroid is a chunk of rock that burn up. They live in the Atmosphere. Also could be a meteor which is the surface of a planet or moons. Well they live in space too as a meteorite.
Comets are snowballs of frozen gases that is 12 miles, 20 km, in diameter. A comet has 2 parts to it a head, which is in front of the tail ad normally dissolves as it gets closer to the sun, and a tail, which once it gets closer to the sun it stretches out. it takes 76 earth days for a comet to orbit the sun.
