Because the planets are not rotating very fast.
A day is defined as the time it takes a planet to rotateonce on it's axis.
A year is defined as the time is takes a planet to revolvearound the Sun.
Mercury is in a 3:2 orbital resonance with the Sun and rotates 3 times for every 2 times around the Sun.
Venus rotates so slowly, that by the time it has rotated once, it has gone around the Sun 1.085 times.
What else can I help you with?
What takes longer one year in venus or mercuty?
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.
Venus year is 225 days long?
yes it is because it is closer to the sun but it day is actually 243 earth days and so its day is longer than its year.
How long is one year on venus compared to earth?
I look in my almanac and its says its 224.7 days.Hope this help! :)
Which planet's day is closest in length to its year?
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.
How long is one in a year on Venus?
One year on Venus is about 224 Earth days.
Which planets day is more than half as long as its year?
It's Mercury or Venus depending on whichthe definition of "day "you mean.
About how long is a year on planet Mercury compared to Earth?
0.2408 of an Earth year.
Which planets have days that are longer than 24 hours?
i am pretty sure Mercury, venus, and Pluto
How long is mercury's year compared to earth's year?
Mercury take around 87.97 days to make one orbit of the sun, about 3 Earth months for one year on Mercury.
Distinguish planet Venus from Mercury?
Mercury is much closer to the sun than Venus. It has less of an atmosphere, much higher temperatures, and a very short year. Venus has an very sulfur-rich atmosphere, cooler temperatures than Mercury, and a longer year than Mercury.
What takes longer one year in venus or mercuty?
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.

Mercury and Venus .
What planet day is more than half as long as it's year?
It's Mercury or Venus, depending on which definition of "day" you use.
Which planets day is half as long as its year?
Venus or Mercury, depending on the definition of "day" used. It takes Venus 243 Earth days to spin on its axis relative to the background stars (a "sidereal day"). It takes Venus 224.7 Earth days to orbit the Sun (its year). However, a "solar day" is only 116.75 Earth days long due to the combination of rotation time, orbit time and spin direction. (Venus spins in the other direction to Earth and most other planets.)Mercury has a "sidereal day" of about 58.6 Earth days and a year of about 88 Earth days.
Venus year is 225 days long?
yes it is because it is closer to the sun but it day is actually 243 earth days and so its day is longer than its year.
Which planets year is 248 days long?
No planet in our Solar System has 248 days in a year.The closest are:-Venus 224 days - although Venus has a day which lasts 243 days.Earth 365 days
