No, there are 14,610 days in 40 years.
Earth, unless you meant days longer than years. In which case, that would be Venus.
15000 MYA means 15000 Million Years Ago, or 15 billion years ago, longer than the approximate age of the universe (13.8 billion years). MYA can also be represented by the SI value "Ma" meaning mega-annum, so that 15000 Ma = 15 Ga (giga-annum).
Jupiter's days are not, in fact, longer than its years. Jupiter's days last about 10 hours, and its year is approximatley 11 Earth years.
venus!
earth
Pluto(i think)
No planet in our solar system has days longer than one Earth year. Venus has the longest day -- it's 243 Earth days.
No the days are longer in June
One interesting fact about Venus is that a day on Venus is actually longer than a year on Venus. A Venusian day lasts 243 days, and a year is 224 days. That means that the day on Venus is 19 days longer than the year.
Venus has a rotation (spin) time of 243 Earth days, and a revolution (orbit) time of 224.7 Earth days, making it the planet with longer days than years.
Every planet's year is longer than 365 days except for Mercury and Venus. Earth's year is aproximately 365.25 days, people just combined them for an extra day every 4 years.
A day on Mars is less than an hour longer. Venus and Mercury have far longer days.
