Proportionately less, yes.

What are the jovian planets vs terrestrial?
"Jovian" planets are considered to be mainly made up of various gases, and are also known as "gas giants". The Jovian planets are known as "Jovian" from the largest gas giant in the solar system: Jupiter. Jupiter, Saturn, Neptune, and Uranus (Haha, very funny) are all considered Jovian planets."Terrestrial" planets are thought of as rocky. A human being could maybe walk on its surface, in a goodspace suit.Terrestrial planets are planets like Earth. The terrestrial planets in our solar system are Mercury, Venus, Earth and Mars.I know I sound like a book, but so-be-it.
What is the primary difference in composition between the Sun and the terrestrial planets is?
Dependant on how the debris from supernovae is moving, the proportions of certain materials present, and the initial conditions of solar systems forming different combinations of terrestrial and Jovian planets are formed. Terrestrial planets are comprised of heavier particles (ie. of higher relative atomic mass) meaning they have stronger gravity which leads to higher density planets than the gaseous Jovian planets. A Jovian planet can be thought of as a failed star - it has all the elements needed to fuel nuclear fusion, but not enough gravity to attain the nuclear activation energy required. So the Sun started as a large cloud mostly comprising of gases, and terrestrial planets were formed from clouds mostly consisting of heavy solids.
What is the largest terrestrial planet?
A terrestrial planet is one like Earth, Mercury or Mars, a solid, rocky planet-- not a gas giant like Jupiter. Earth is the largest one in our solar system, however larger planets have been observed outside our solar system that are thought to be terrestrial, such as Gliese 436 c.
What are lunar rays?
Lunar rays are bright bands of material thrown out very large distances from impact craters on the Moon. They are also seen on other planets, notably Mercury. They are thought to represent ejected material with a high level of iron oxide and similar materials.
Who thought that the earth was the centre of the universe and that the planets had circular orbits?
Ptolemy, but he was wrong the sun is in the center and planets have elliptical orbits.
What is difference between the terrestrial and gaseous planets?
A terrestrial planet is made of rock, in which there is life on. However, a gaseous planet is made of gas, in which there is no life on.
A being thought to be from outer space?
Imaginary, or deluded; take your pick. No one seriously believes in extra-terrestrial visitors from other planets.
How where the asteroids in the solar system made?
It is thought that Asteroids are leftover material from unfinished planets.

Similarities between monera and protists?
There are only two that i have thought of...........They are both simple organisms and they both contain heredity material There are only two that i have thought of...........They are both simple organisms and they both contain heredity material

How are the planets of the solar system often grouped?
The planets are often grouped as the "inner planets" and the "outer planets" or as the "rocky planets" and the "gas giants." The inner planets are Mercury, Venus, Earth, and Mars. The outer planets are Saturn, Jupiter, and Uranus. (Pluto was an "outer planets" until it was redefined as a planetoid. Now that Pluto is not considered to be a planet, the outer planets are the same as the gas giants, and the inner planets are the same as the rocky planets. (Pluto was thought to be a rocky planet, or, at least, not a gas giant.
What is the largest terrestrial planet?

What is Mercury the planet made out of?
The inner or terrestrial planets are mostly rock (sliicates) and metals; Mercury is no exception. It is thought to have a relatively large iron core.
What is the significance of ALH84001?
That is a meteor that is thought to contain material from Mars. There are some claims - controversial ones - that it contains remainders of Martian (microbial) life.
Why do the inner terrestrial planets have far fewer moons than the gas giants?
The smaller planets (Earth and Mars) have a smaller gravitational attraction than the larger planets, which limits the potential orbital distance. They are also closer to the Sun, where there are comparatively fewer asteroids, and where the gravity of the Sun and nearby planets make stable orbits less likely. While the Moon is thought to be made from material once part of the Earth, the tiny moons of Mars (Phobos and Deimos) are likely asteroids that came close enough to the planet to be held there. They are in comparatively low orbits, only 6000 and 23000 kilometers, respectively, from the Martian surface.
What is the density on average of a terrestrial?
First things first: I'm not sure what a "terrestrial" is. I assume you left out the word "planet", and this answer will address that. The density of "terrestrial" planets varies quite a bit. Earth's average density is about 5500 kg per cubic meter, but that of Mars is only about 3900 kg/cubic meter. The Moon is thought to have been created by the impact of an approximately Mars-sized body on the proto-Earth as it was forming, and a lot of the lighter material "splashed" into orbit and formed the Moon, so it's even less dense (about 3350 kg/cubic meter). In our own solar system, for terrestrial planets the density goes up with size generally speaking, though Mercury is nearly as dense as Earth despite being the smallest planet. This is probably because it's so close to the Sun that the lighter more volatile elements have been vaporized and driven outward by the solar wind and radiation pressure.
