Venus, the second planet from the sun, is named for the Roman goddess of love and beauty.
The planet — the only planet named after a female — may have been named for the most beautiful deity of her pantheon because it shone the brightest of the five planets known to ancient astronomers.
The average temperature of Mercury is about 442.5K whereas Venus has an average temperature of 735K. The reason for these temperatures being the presence of atmosphere in Venus and absence of atmosphere in Mercury. Venus has the thickest atmosphere in our Solar system. The atmosphere mainly consists of Carbon dioxide and some Nitrogen. The carbon dioxide rich atmosphere generates the strongest greenhouse effect in our Solar system, which means that heat will be trapped inside. Also, as the heat is trapped inside, the weather spreads the heat across the whole planet and therefore, the whole planet has a temperature of about 735K.
It is a completely different story in Mercury. As it has no atmosphere to trap the heat from the Sun, the temperature ranges from 90K to 700K. This means that it has got one of the hottest and the coldest temperatures in our Solar system. This is because, the side facing the Sun receives the heat directly and it is hot and, other dark side of Mercury receives no heat from the Sun and it has no atmosphere to trap heat which makes it extremely cold. And this is why Venus is hotter than Mercury.
