What else can I help you with?
A day is longer than a year on this planet?
On this planet, a day is longer than a year because the planet has a very slow rotation on its axis. This means it takes longer for the planet to complete one full rotation (a day) than it does to complete one orbit around its star (a year).
Which planet takes 248.5 earth years to go round the sun?
The planet that takes 248.5 Earth years to orbit the Sun is Neptune. It is the eighth planet in our solar system and has a very long orbital period due to its distance from the Sun.
The planet where sun never rises nor sets?
The planet where the sun never rises nor sets is Mercury. This is because Mercury has a very slow rotation compared to its orbit around the sun, so one side of the planet always faces the sun while the other side is in perpetual darkness.
A year is only 88 earth days on which planet?
A year on Mercury is only 88 Earth days. Mercury is the closest planet to the Sun and has a very short orbital period, causing its year to be much shorter compared to Earth's year of 365 days.
What is the first inner planet?
The first inner planet is Mercury. It is the closest planet to the Sun in our solar system and is known for its extreme temperature variations, ranging from very hot to very cold.
Which planet rotates very quickly?
The planet with the highest rotational speed in our solar system is Jupiter, with a period just under ten hours.
Is there any planet which have same rotational and revolution periods as earth?
No. Mars has a similar rotational period but not revolution. For a planet to have the same revolution period as Earth would mean it would have to be in the same Orbit as Earth, with catastrophic results. One was in the same orbit as Earth during it's formation, it crashed into the Earth creating the Moon. It's possible that some extrasolar planet (that is, a planet of a star other than the Sun) might by coincidence have nearly the same rotational and/or revolution period, but we don't know of any yet (and it's not very likely that we ever will).
What is the relationship between the centripetal force and rotational period?
A very close one.
Why doesn't Venus have a magnetic field?
Venus does not have a magnetic field because its rotational period is very slow. This means that if its core had a liquid metal component, it would not be moving fast enough to generate a field.
A period when economic activity is very slow?
Recession! I had this for a test.
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.
What is the length of a day on Haumea?
A day on Haumea is very short compared to here on Earth. Haumea's rotational period is just 3.9155 hours.
What planet has twice the earth's period of revolution?
Mars has an orbital period of very approximately twice that of the earth
Does movie and tv planet give viruses?
no, i used it for about 3 weeks, very reliable. Downloads are VERY slow though.
Why does Venus rotation -243 days mean?
The planet Venus spins very slowly in the opposite direction of almost everything else in the solar system. That's what the minus sign next to its rotational period means; it takes 243 days to spin, and spins "backward".
How does it takes venus to rotate on its axis?
I think the exact number is 257 earth days. Venus has a very slow retrograde rotation, so the number is written usually thus; - 257 earth days.
What is a star that is a?
They're called pulsars. Some pulse very quickly - some have a long period between pulses. It depends on the rotational speed.
