How were the planets named?
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. Jupiter, Saturn, Mars, Venus and Mercury were given their names thousands of years ago. The other planets were not discovered until much later, after telescopes were invented. Mercury was named after the Roman god of travel.

Why are Mercury Venus Earth and Mars called the terrestrial planets? They are called terrestrial because they are “Earth-like” (Latin Terra, or Earth). The four inner, rocky planets are known as the terrestrial planets because they have a clearly defined terrain (unlike the four outer gas giant planets).
How big is Mercury compared to Venus and Mars?
In fact, Mercury’s density implies that at least 60% of the planet is a metal-rich core, a figure twice as great as for Earth, Venus, or Mars! To account for about 60% of the planet’s mass, the radius of Mercury’s core must be approximately 75 of the radius of the entire planet!
Which is the smallest planet Earth Venus or Mars?
Mercury, Venus, Earth, and Mars are terrestrial (rocky) planets. Among these, Mercury is an extreme: the smallest, the densest (after correcting for self-compression), the one with the oldest surface, the one with the largest daily variations in surface temperature, and the least explored.
What kind of atmosphere does the planet Mercury have?
Mercury is a rocky planet, also known as a terrestrial planet. Mercury has a solid, cratered surface, much like the Earth’s moon. Mercury’s thin atmosphere, or exosphere, is composed mostly of oxygen (O2), sodium (Na), hydrogen (H2), helium (He), and potassium (K).
