Mercury's axis tilt is 0°. Venus' axis tilt is 177.4°. Earth's axis tilt is 23.5°. Mars' axis tilt is 25.2°. Jupiter's axis tilt is 3.1°. Saturn's axis tilt is 25.3°. Uranus' axis tilt is 97.8°. Neptune's axis tilt is 28.8°. Pluto's axis tilt is 122.5°.
which planet has the slowest orbital velocity
The planet with the axis of rotation which gives it almost no tilt is "Mercury". "Mercury's" axis of rotation has a tilt of 0 degrees. The planet "Jupiter" has very little tilt due to its axis of rotation at only 3 degrees.
Each planet in our solar system has a unique axial tilt, ranging from nearly 0 degrees for Mercury to about 98 degrees for Uranus. The axial tilt is the angle between a planet's rotational axis and its orbital plane. This tilt affects the planet's seasons and climate.
Jupiter's axis of rotation is tilted at an angle of approximately 3.13 degrees relative to its orbit around the Sun. This tilt is relatively small compared to other planets in our solar system.
Dwarf planet Pluto has an extreme axis tilt, rather like the planet Uranus. The tilt is about 120 degrees.
Mercury, with an axial tilt of ~0.01
Mars is tilted at 25.19°, which is pretty close (slightly greater) than earth's 23.44° tilt. That "tilt" is the angle between the axis of rotation and the line perpendicular to the plane of the planet's orbit.
12.5 degrees
It is about 23.5 degrees
The season with the highest angle of insolation is summer. This is due to the Earth's tilt on its axis, which causes the Sun's rays to be more direct during summer months in each hemisphere.
