In general terms a day for a planet is the time taken for the planet to make on rotation on its own axis.
Likewise a year for a planet is the time taken for the planet to make one orbit (rotation round) its primary star.
Where a planet is tidally locked to its primary, the day length and the year length will be the same, such that the planet keeps one face permanently towards it primary (like the Moon does to the Earth).
I`ll assume by a day you mean an Earth day (24 hours). Saturn rather !
Day of Wrath
Habitable Planet? I do not believe there is a more specific term for a planet capable of supporting life.
A "day boat" is a term usually used for a fishing charter that goes out for the day, as opposed to hourly or overnight. There may be other definitions.
Line, if you mean a planet's axis as in earth's north pole and south pole.
The French term "bonjour" translates to "good day" or "hello" in English. It is a common greeting used throughout the day in French-speaking countries.
it is par day wage
This is planet Earth, so one Earth day is one day on this planet.
no,planet has a star day and night
If you mean "which side of planet Earth", that changes all the time, as Earth rotates.
Mars. The Martian "sol" (we don't call it a "day" to preserve that term for a particular unit of time) is about 24.66 hours, just a bit longer than an Earth day.
I think you mean "Venus". That planet rotates in about 243 Earth days. That is one definition of a "day". It is called the "sidereal day". There is another definition called the "solar day", which takes into account the planet's motion around the Sun. For Venus this is about 117 Earth days long.
