What does the earth make one of on its axis everyday?
The Earth makes one complete rotation on its axis every day, which causes day and night to occur.
How much earth days are in a ganymede day?
One Ganymede day is approximately 7 Earth days. Ganymede, Jupiter's largest moon, has a longer day due to its slower rotation compared to Earth's.
What is the scientific definition of day?
It is the 24 hour period, for planet Earth. An hour is 60 minutes and 1 minute equals 60 seconds. 24 hours is called the "solar day". It depends on the Sun's position in the sky. There are other definitions of "day" The "sidereal day" is equal to the Earth's rotation period. That's about 4 minutes less than the solar day. That's because the solar day depends on the Earth's motion around the Sun as well as Earth's rotation. Other planets have their own day lengths.
How many days does the earth take to spin round?
The Earth takes approximately 24 hours to complete one full rotation around its axis, resulting in a day-night cycle.
How days are on earth?
The length of the day on Earth is governed by the rate of spin upon its axis. This is our definition of a day - currently about 24 hours. In ancient times, the day-length was much shorter; then the Moon collision occurred, and the days from that point became slightly longer. The moon collision was possibly the slow collision of another Mars-sized body with the Earth, the debris from which created the Moon. This was quite soon after the creation of a separate Earth, about 4.5 billion years ago. This created gravitational tides on both bodies, Moon and Earth. On the Earth, the energy of these tides are presented as energy released by tidal friction - a minuscule warming of the oceans. On the Moon, the energy of these tides (for both must be equal) is seen as a gradual increase in the distance between Earth and Moon. And of course, this gravitational attraction also causes the more massive part of the Moon to present only one face constantly to the Earth. So:- in the long run, the oceanic tides will lessen (minutely); the day-length will increase slightly; and the Moon will drift further away from the Earth.
How many days on Mercury is equal to one day on Earth?
Mercury rotates once in about 59 Earth days. That is often called its "day". There's another definition of day called the "solar day". For Mercury that's 176 Earth days. So, you can see there's only a small fraction of a Mercury day in one Earth day.
What is the length of venues 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.
What planet is only one AU from the sun?
By definition, it's the Earth.
How long does one day last in earth?
Solar day . . . 24 hours (definition) Sidereal day . . . 23hours 56minutes 4seconds (units defined by the solar day)
What planet rotates on its axis in one day?
The Earth rotates on its axis in one day. Strictly speaking that's the "sidereal day" not the "solar day". Also, by definition, each planet rotates once in a period that's the "sidereal day" for that particular planet.
How many earth days is one day on this planet?
This is planet Earth, so one Earth day is one day on this planet.
Waning moon definition?
A moon that is reducing in the size, of the illuminated surface visible to earth, day by day.
What is the name of the planet with the longest day compared to an earth day?
Venus. The length of "day" is 243 Earth days. That's the rotation period which is called a "sidereal day". However, there's also a "day" called the "solar day". That's the time for the Sun to complete one apparent journey around the sky. For that definition of "day", it is Mercury that has the longest day at about 176 Earth days.
What is the period of revolution for the earth in earth years?
Earth's rotation takes exactly one Earth year (definition).
What is mercury's length of day?
Mercury rotates once in about 58.6 Earth days. That's one definition of its day. However, Mercury's "solar day" lasts about 176 Earth days. That "day" is based on the position of the Sun in the sky. It depends on Mercury's orbital motion as well as its rotation on its axis.
How many earth years does it take earth to revolve around the sun?
By definition, one.
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.
