Which planet is the fourth planet from the Sun?

Which planet is the fourth planet from the Sun?

• A. Mercury
• B. Mars
• C. Earth
• D. Venus

Answer: (B)

Think about how planets line up by distance from the Sun. If you start at the Sun and move outward, the order is Mercury, then Venus, then Earth, and Mars comes after Earth as the fourth. So Mars is the fourth planet from the Sun. Mercury is closest to the Sun, Venus is next, and Earth is third, which is why those options don’t fit. Mars being the fourth fits the sequence perfectly.
