Plz make clear ur question !

No. One minute means one minute or one second means one second wherever u count. But in earth a day is in 24 hour which can be more or less for other planet or we count a year in 365 days which can be more or less for other planet as it is the time in which a planet make a round of sun. That is a different thing.
If a planet take more time to make a round of sun it does not mean its time is slow as there is more day in a year.

If the other planet is more massive, time will run faster here. But the difference is very small.

In order for god s plan to work, earth is a time accelerator, it has been proven. Time actually moves faster here, than anywhere else in any galaxy. Making our planet much older than anything else out there. The truth is the truth, whether you choose to believe it or not.

One of the effects of gravity predicted by Einstein in his theory of general relativity, and verified by experiment, was that time slows down in a gravitational field. So time on Earth runs slightly slower than time in space. Not enough that the astronauts need to reset their watches, but enough that the clocks on the GPS (global positioning system) satellites needs to be corrected for the difference.

No. Other planets run with the time at their own speed.

Time is all relative...depending on your position, time could be moving faster or slower. For example, if you had an identical twin in a spaceship moving away from earth at 4/5 the speed of light for 25 years in his or her frame of reference, then returning to earth, he or she will return to earth to meet not you, but your great (to the nth degree) grandchildren, because time for that person in relation to your time (though they watched the clock ticking at regular speed and they didn't even notice it) slowed down considerably.

Now that we've had the scoffing, the vaguely philosophical and other responses, it's time to take the question seriously and see what modern science has to say about the rates at which time runs on our own and other planets in the solar system, both relative to each other and to empty, deep (far distant) space.

In what follows, S.R. means Special Relativity (or Special Relativistic), G.R. General Relativity (or General Relativistic). There are two relevant S.R. or G.R. effects that each slow down time with respect to a reference rate for a "stationary observer" out in deep, empty space to which we can easily refer all of the rates at which time runs.

In the solar system, these effects are so small that after giving the S.R. or G.R. expression for each one, I'll immediately write its "slow speed, weak field" or " ~ " approximation.

1. The theoretical basis; two types of changes in the rate at which time runs, depending on individual circumstances.

A. Speed. This S.R. effect goes as sqrt[1 - (v/c)^2], or:

Speed effect on time ~ [1 - (1/2)(v/c)^2]. ......(A)

For the Earth in orbit, with v its orbital speed,v/c ~ 10^(-4) or 0.0001. So you can see what a small effect this is; (1/2) (v/c)^2, the FRACTIONAL REDUCTION in the rate at which time runs is ~ 1/2 10^(-8) or ~ 5 x 10^(-9) ! It's ~ (1.6)^2 or ~ 2.6 times this for Mercury; and ~ (0.44)^2 or ~ 0.2 times this for Jupiter.

B. Place. This G.R. effect is due to being at some depth in what is in effect a gravitational well. It's a later generalization of the first order effect that Einstein discovered using the Equivalence Principle. Its strength is given by sqrt[1 - {2 G M / (r c^2)}], or, in weak fields,

Place effect on time ~ [1 - {G M / (r c^2)}].

Here G is the Gravitational Constant, M the mass, and r the current "radial coordinate" or radial distance from the centre of M. (This ignores a technical detail that need not concern us.)


2. Time-rate differences on the surface of a given planet.

I'll take account of three effects: The orbital speed of the planet (S.R., type 1.A. effect) and the gravitational wells of both the Sun and the planet itself (G.R., type 1.B. effect). Many other effects, such as planetary rotation, are also needed in particular for really accurate results on Earth such as with GPS satellites or the scientific monitoring of signals from pulsars. However, they're minor compared to the main terms.

All these terms multiply together. Becuse they are small, the net result is:

1 - [(1/2)(v_orb/c)^2 + G M_s / (R c^2) + G m_p / (r c^2)].

So, the FRACTIONAL REDUCTION in the rate at which time runs on the surface of a planet is:

[(1/2)(v_orb/c)^2 + G M_s / (R c^2) + G m_p / (r c^2)].

Here, v_orb is the planet's orbital speed (orbit assumed circular) , M_s and m_p the masses of the Sun and planet respectively, R the orbital radius, and r the planet's radius.

This three term expression properly illustrates the origin of each term. However, for calculational purposes it's convenient to express everything in terms of an associated velocity. (My data source lists the orbital speeds and escape velocities of planets in the solar system.)

NOTE CAREFULLY: It should NOT be thought that all the "v's" in the following arise originally just from velocity effects.

For an orbiting planet,

(v_orb)^2 = G M_s / R,

while its own escape velocity, v_esc, is given by:

(v_esc)^2 = 2 G m_p / r, or G m_p / r = (1/2) (v_esc)^2.

So the fractional time-rate reduction,

[(1/2)(v_orb/c)^2 + G M_s / (R c^2) + G m_p / (r c^2)],

works out to be:

[(3/2)(v_orb)^2 + (1/2) (v_esc)^2] / c^2.

Here, to the 3 sig. figs. justified by the data, is a table of the planets, the values for their fractional time-rate reductions (times 10^8), and their time-rate rank ordering, from fastest (1) to slowest (8). (Unfortunately, column spacing is spoiled in the final view.)

PLANET REDUCTION RANK
Mercury 3.83 8
Venus 2.10 6
Earth 1.55 5
Mars 0.982 4
Jupiter 2.26 7
Saturn 0.858 3
Uranus 0.329 1
Neptune 0.363 2

Up till Mars, v_orb and the Sun's gravitational well give the dominant effect. The ordering, moving away from the Sun, is from having the slowest to the fastest time rate due to both decreasing orbital speed and the climb up out of the Sun's gravitational well. Jupiter, however, bucks this trend; its escape velocity is comparatively huge. (That means of course that it has the deepest gravitational well of all, due to itself, out of which to have to climb up. Whereas Mars has average v_orb = 24.1 and v_esc = 5.0 km/s, Jupiter has average v_orb = 13.1 and v_esc = 59.6 km/s.) Uranus has the most shallow gravitational well of the remaining three planets(sorry for the demotion, Pluto), and that plus its low orbital velocity makes it top of the class as far as the rate at which time runs on it is concerned.So Earth is 5th in the table. Time on our planet Earth runs faster than that on Mercury (slowest), Jupiter and Venus, and slower than that on Mars, Saturn, Neptune and Uranus (fastest), in that order.

Of course, on Earth you'd have to wait ~ 2 years before an Earth-based clock was running slow by 1 second compared with an identical clock in deep space, and comparable times when comparing slow or fast running with identical clocks on the other planets. If you and a friend had watches that agreed that well after 2 years, you'd think it would almost be miraculous.

Thank you for a most interesting and stimulating question; I'd never examined this before.

Live long and prosper.

time is the fundamental referentiable quantity of d universe taken on convenience by humans as seconds,minutes,etc...it cant go fast or slow.for example,if in a planet d length f d day is only 14hrs,it isnt d time being fast,but tis d rotation f d planet being fast.

yes.because earth is closer to the sun than other planets in our solar system.earth is the 3 planet from sun as you know.so it takes less time to go round the sun than the inner planets like mars,juiter,neptune,satrun etc.mars takes 37 minutes more than the time taken by earth to complete one circle round the sun.

Time is a dimension created by humans. We are unable to contemplate life without time. As time is a human invention it is standard everywhere.
