Explanation

One day on Venus (one full rotation) takes about 243 Earth days.

Venus takes about 225 Earth days to orbit the Sun, making a day on Venus longer than its year.

So, 1 day on Venus ≈ 1 year on Earth (approximately).

Explanation

Order of Planets from the Sun (by distance):

• 1st: Mercury
• 2nd: Venus
• 3rd: Earth
• 4th: Mars

Explanation

A light year is the distance light travels in one year — about 9.46 trillion kilometers.

It is commonly used to measure vast distances between stars and galaxies.

Astronomers use an effect called parallax to measure distances to nearby stars.

Parallax is the apparent displacement of an object because of a change in the observer's point of view.
