Of course. They had to come from somewhere, and that somewhere was probably the supernova that gave our molecular cloud that "little" nudge, that was required for the Solar System to start forming.

Why do the inner planets have more of the lighter elements like hydrogen and helium gas like the outer planets do?
The Sun and its planets formed form a huge cloud (disk) of dust which contained both light and heavy elements, but there were more light elements (hydrogen) than heavy. As the disk coalesced into the sun and planets the areas close to the young sun were too hot (heated by the sun) for the light elements to condense and settle onto the young inner planets which are therefore rocky, while the outer planets being further from the sun did accumulate the lighter and more volatile elements. However in the centers of the giant planets there are rocky (heavy) cores.
What is different between gas giants and terrestrial?
Terrestrial planets contain much more of the heavy elements (such as iron and silicon) and less of the lighter elements (such as hydrogen and helium). Terrestrial planets are smaller and denser, and are also closer to the sun, and hence warmer as well. Gas giants are distant and cold.
Why are the inner planets made of heavy materials?
The Inner Planets dense and rocky because they are close enough to the sun that the heat has driven off the free hydrogen and helium which forms most of the Gas Giant planets (and most of the universe). Only the heavier elements remain.
What are three similarities among the inner planets?
Compared to the outer planets (gas giants), the four inner planets are small, have a greater average density, and receive most of their heat from the Sun. Mercury, Venus, Earth, and Mars are compact rocky planets, with a solid surface rather than a thick atmosphere. Their masses give them less gravity, but they contain a greater percentage of heavy elements, such as iron and zinc, than the larger planets. Without the Sun's radiation, their surfaces would be considerably cooler, as can be seen by the lower temperatures on Mars compared to Mercury and Venus.
Why are planets closest to the sun largely devoided of lighter elements?
The lighter elements turn to gas at a lower temperature and because of their lack of atmosphere are released from the planets out into space
Which solar system bodies contain mostly H and He gases?
The Sun and the jovian planets.
Is stars the size of the sun can produce elements heavier than oxygen true or false?
True. Our Sun will eventually produce elements as heavy as iron.
What are theories of the origin of earth?
It was long thought that the earth and all the planets in our solar ssystem were formed as the sun itself was formed. However, young stars consist almost entirely of hydrogen, and this early theory would not account for the quantity of heavy elements in the earth's crust and atmosphere. In fact, an average star like the sun does not produce very heavy elements at all. Cosmology explains how the earth was formed. At some stage, a supernova star exploded in the neighbourhood of our sun - within a few million light years from here. Supernovas are formed as giant stars die and are not entirely uncommon. And giant stars, because of their far greater mass, are able to convert their hydrogen into heavy elements before finally dying. Conversion of hydrogen into heavy elements is also well known to nuclear physicists. So, our supernova exploded and sent an enormous amount of heavy elements out into empty space. A very small part of this was captured in orbit around our sun, where it eventually concentrated into the various planets and other bodies that orbit the sun. One of these was, of course, the earth.
What are the inner planets made up of in the solar system?
The eightplanetsthat orbit the sun are (inorderfrom the sun): Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.The inner planets are heavy element planets with mainly an iron core. Earth and Venus have an abundance of gases for an atmosphere although the Venusian would be unbreathable for humans. The outer planets are all "gas giants" with various elements at their center surrounded by enormous layers of gases.
Why are the planets called the sun family?
The planets in our solar system are sometimes considered the Sun's Family due to the fact that they all orbit the sun (the star at the center of our solar system). When thinking about this also consider planets that do not orbit a star (rogue planets), so is the sun's family just relating to our solar system? Another way to look at the term is the fact that all planets are 'children' of stars. During the life of a star, the heat and pressure turns light elements into heavy ones until Iron is formed. Once this happens, the death of the star in imminent and the star explodes, shooting its guts (all the elements created) into space which through the process of millions of years forms planets... and us! So everything can be considered the children of stars ;)
What elements does the Sun's heat contain?
The sun is mainly composed of hydrogen and helium, and the sun's heat carries those atoms with it.
What are the chemicals made up of the sun?
Sun contain hydrogen and helium and low concentrations of other elements..
