What causes days months and years?
The Earth’s orbit around the Sun takes 365.24 days. A ‘day’ is defined as the Earth spinning once on its axis. The Earth takes approximately 365.25 days to go around the Sun, yet our calendar year is 365 days. To fix this, we put on extra days in some years, called leap years.
Which planet has the longest year?

What planet has the shortest days?
planet Jupiter
What planet is the hottest?
Venus
Is Venus hot or cold?
The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius). Temperature changes slightly traveling through the atmosphere, growing cooler farther away from the surface. Lead would melt on the surface of the planet, where the temperature is around 872 F (467 C).
How close is Venus to Earth today?
kilometers
Why is Venus called Earth’s sister?
Venus is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects.
Do we have 2 suns?
The idea of a second sun in our solar system is not as bizarre as it might sound. Binary star systems (two stars orbiting the same center of mass) are quite common. In fact, Alpha Centauri, our solar system’s nearest neighbor, is a binary system

Is Venus visible every night?
Venus is always the third-brightest object in the sky behind the sun and the moon, and it’s always brighter than the brightest stars. However, because it orbits relatively close to the sun, it’s only ever visible for a short time after sunset or before sunrise
Why is Venus visible at night?
Because the outer planet’s orbit is outside the orbit of Earth, one can see it at any time of the night. There is a maximum angle between the Sun and the planet in the sky and that happens when the planet subtends a right angle between Earth and the Sun.
Is Venus visible year round?
It appears in the evening in the western sky at dusk from May 24 to Dec. 31. When the year opens, it will be visible very low near the east-southeast horizon about 90 minutes before sunrise. Venus will be out of view until late spring when it emerges above the west-northwest horizon soon after sunset.
Can we see Venus now?
Venus is hard to see because she sits low at dusk, and follows the sun beneath the horizon before darkness falls. Mercury is difficult to view as well, because the solar system’s innermost planet transitions from the morning to evening sky in April 2021
