The length of a planet's day is determined by the speed of it's rotation on it's axis. The faster the rotation, the shorter the day. The slower the rotation, the longer the day. This is affected by many factors such as any moons the planet may have (orbital speed, rotation speed or tide lock, distance and direction of travel of the moons all should be considered), past collisions with other large bodies (planetoids and other planets and their moons), and how the stellar dust and debris were moving and colliding when the planet was formed. Some planets are tide locked to their star and have no rotation and therefore no relative "day". One side faces forever toward the blazing heat of it's star, while the other side faces an eternal frozen night.

Why do some planets have shorter length of days than Others?
The length of a planet's day is primarily determined by its rotation speed on its axis. Some planets, like Jupiter, rotate much faster than Earth, resulting in shorter days, while others, like Venus, have extremely slow rotations, leading to longer days. Factors such as a planet's size, composition, and the influence of gravitational interactions can also affect its rotational speed. Additionally, events in a planet's history, such as collisions or tidal forces, can alter its rotation over time.
Which planet has a year that is shorter than its day?
There is some confusion on this matter. Because of its spin-orbit resonance and fast orbit, an observer on Mercury would see only one day every two years. Venus has the slowest rotational period of any planet in our solar system at 243 days, and it completes an orbit in 224 days, so its sidereal day is longer than its year - but note that because of its retrograde motion (it rotates upside down, or spins the opposite direction it orbits), an observer of Venus would see almost two days per Venusian year, so its solar day is shorter than Mercury's.

Why do planets have shorter days than earth?
The length of a planets "day" is another way of saying the amount of time it takes a planet to rotate once on it's axis. Each planet does this in it's own good time. There are some basic principles behind it, but overall, there is no "one answer" we can pinpoint as to why planets rotate at different speeds. They simply do.
What planet has a tilted axis so that the planet has seasons .?
All planets have seasons. Some have longer and shorter seasons then others. On some planets a day is longer then its season. Of the "inner planets" only Earth and Mars have large enough tilts to give significant seasonal effects.
Which planet is some times called your sister planet?
Venus is the sister planet of the earth
How do you live on earth if earth is a planet?
Some planets are too far from the Sun, and some are too close to the Sun, while planet Earth has the perfect spot for life.
Orders of the planets?

When was Earth the planet discovered?
The earth as planet was discovered by some of the ancient astronomers. Nicolaus Copernicus and Ptolemy are credited with provision of the initial information of the earth as a planet in relation to the solar system.
Is Pluto a planet or some type of satellite?
Pluto is a dwarf planet, so it is technically, it is not a planet like earth or mars.
What are some characteristics of planet earth?
Planet Earth is the third planet from the sun in our solar system. It is the only known planet to support life and has a diverse range of ecosystems and climates. Earth has a unique atmosphere that contains oxygen, allowing for the existence of living organisms.
