The inner planets of the solar system, also known as terrestrial planets, are those located closer to the Sun.
These are Mercury, Venus, Earth, and Mars.
They are called terrestrial due to their rocky composition and solid surfaces.
Mercury is the closest to the Sun, but its temperature varies drastically. Venus is extremely hot due to its thick carbon dioxide atmosphere.
Earth is the only known planet with life, and Mars, nicknamed the “Red Planet,” has been the subject of exploration for signs of past or present life. These planets are crucial for understanding the evolution of the solar system.
