The planet Mercury has a day that is almost the same length as its year. Mercury's rotation period is about 59 Earth days, which is very close to its orbital period around the Sun of about 88 Earth days. This means that one day on Mercury is almost as long as one year on Mercury.
If you define a "year" for a planet as the length of time for it to make one revolution around the sun (the sidereal period) the "years" for the two planets are: Mercury 0.241 earth year (88.0 days) Venus 0.615 earth year (225 days) ... so Venus has a longer "year" than Mercury.
To understand the length of a day on Mercury, it is important to know the length of a Mercurian year. (Actually you don't need to know that.) Mercury orbits the sun in about 88 Earth days. It rotates on its axis (day) three times for every two orbits around the Sun (year). A Mercurian year lasts about one and a half Mercurian days. That's about 58.65 Earth days for the length of a day on Mercury. Remember though that this is called a "sidereal day". There's also another day called the "solar day". This is based on the apparent journey of the Sun round the sky. For Earth these two days are only slightly different, but for Mercury the difference is huge. The solar day is about 176 Earth days on Mercury.
It is approx 88 Earth-days.
The length of one year (one revolution around the Sun) onMercuryis 88.0 days.
It is approx 88 days.
5 days
One year on Mercury is about 88 Earth days long, 3/4 of a Mercurian day.

88 days
idk bout years but it's 88 days
