The correct answer is option 1: Venus. Venus is the brightest planet in our solar system. There are several reasons why Venus appears so bright. Firstly, Venus is the closest planet to Earth, which means it reflects a larger amount of sunlight back to us. Secondly, Venus has a thick atmosphere that acts like a mirror, reflecting more sunlight. Lastly, Venus has a high albedo, which means it reflects a significant amount of light. Despite being the brightest planet, Venus is not the hottest planet in our solar system. That title goes to Mercury, which is closer to the Sun.
