MCQ Detailed View

Among all the planets in our Solar System, Venus is the most easily visible from Earth without using a telescope. It is often referred to as the “Morning Star” or “Evening Star” because it appears very bright in the sky shortly after sunset or just before sunrise. Venus is the second planet from the Sun, and its high reflectivity makes it shine more than any other planet seen from Earth.

The brightness of Venus is mainly due to its thick cloud cover, which reflects sunlight efficiently. Even though Venus is similar in size to Earth, its atmosphere is filled with carbon dioxide and covered by dense sulfuric acid clouds, making it highly reflective. This allows it to appear brighter than stars and other planets in our night sky.

While Mercury is closer to the Sun, it is often hidden by the Sun’s glare and visible only for short periods during twilight. Mars can also be seen without a telescope, often appearing reddish, but it is not as bright as Venus. Jupiter, the largest planet, is also visible to the naked eye and can appear bright, but Venus outshines all other planets because it reflects more sunlight and comes closer to Earth than Jupiter does.

For centuries, people have observed Venus in the sky, sometimes mistaking it for a star due to its brightness. It is the easiest planet for beginners to spot without special equipment. Its appearance can change slightly based on its position relative to Earth and the Sun, but it remains the brightest planet visible to the naked eye.

Therefore, the correct answer is Option B: Venus, making it the planet most easily visible from Earth.
