Uranus, the blue-green planet, is four times wider than our earth at a diameter the 31,763 miles (51,118 km).

Orbiting in ~ 1.8 billion mile (2.9 exchange rate km) indigenous the Sun, Uranus take away 84 planet years to complete one orbit.

At this distance from the Sun, what walk a day and also a year ~ above Uranus watch like? And, just how long would certainly it take it to gain there?

Let’s find out.

How much Away is Uranus native the Sun?

Planet Uranus is 1.7 billion mile (2.5 billion km) native the sunlight at that closest, and 1.89 billion mile (3 billion km) away at its farthest.

You’ll an alert that there isn’t a far-reaching difference in between the closest and also furthest distances. That’s since Uranus’s orbit is practically circular, with an orbital eccentricity of just 0.04. Top top average, the is 1.8 billion miles (2.9 exchange rate km) far from the Sun, and its closest and furthest distances are not really different from each other.

How much Away is Uranus native the Earth?

Uranus is 1.6 billion miles (2.6 billion km) when it is closest come Earth and 1.98 billion mile (3.2 billion km) as soon as it is the furthest indigenous Earth.

The distance of Uranus indigenous our world varies much much more than its street from the Sun since sometimes we space on the same side that the sunlight as Uranus and, at various other times, we room on the opposite side of the Sun.

When Uranus is directly behind the sun (known together a solar conjunction), Uranus, the Sun, and also Earth room in alignment through the sun in the middle. In ~ this point, Uranus is as much away together it have the right to be native Earth, at nearly 1.98 billion miles (3.2 exchange rate km).

As the 2 planets continue on your orbits, the distance in between them shrinks. Eventually, Uranus’s closest approach to earth occurs when both planets room in line with the sunlight but, this time, earth is between the Sun and Uranus, i.e. Uranus and Earth room on the exact same side the the Sun.

This minute is well-known as Uranus’s opposition. That occurs once per year and also the distance in between Earth and also Uranus at the time shrinks to around 1.6 billion mile (2.6 exchange rate km).

When it is closest come Earth, Uranus shines at magnitude 5.7. Back Uranus is brightest and also largest in ~ this time, that is not feasible to identify it from other stars there is no the aid of a telescope.

How lengthy Would It require to Reach Uranus?

Voyager 2 is the only spacecraft that visited Uranus, and also it take it 9 and a fifty percent years to obtain there. Light, ~ above the other hand, travel to Uranus from earth in just 2.4 hours as soon as the 2 planets space at your closest.

So far, in this article, we have learned the the street from earth to Uranus in ~ two important points in the orbit — one as soon as the earth is closest and the other once it is the farthest. We have the right to now proceed to understand just how long that takes to acquire to Uranus.

There space two ways to go about this. First, we will look at the moment light bring away to reach Uranus native Earth.

Next, we will board a spaceship (imaginatively, that course) and also see exactly how long it’ll take united state to take trip to Uranus

Let’s go!

How long Does Light take to Travel indigenous Uranus come Earth?

Light travels the more quickly of all well-known objects because it has no mass. Its rate is an unimaginable 186,282 miles every second. In ~ this rate, irradiate takes 499 seconds to reach planet from the Sun.

The typical distance between the Earth and Sun is known as an astronomical Unit. Let’s take a look in ~ the shortest, longest, and also the average time because that light to travel between the 2 planets.

Shortest Distance: 1.6 billion miles (2.6 billion km) = 17.2 AU

Calculation: 17.2*499 = 8,583 seconds = 2.38 hours.

Average Distance: 1.7 billion mile (2.5 billion km) = 18.2 AU

Calculation: 18.2*499 = 9,082 seconds = 2.52 hours.

Furthest Distance: 1.98 billion miles (3.2 billion km) = 21.3 AU

Calculation: 21.3*499 = 10,629 secs = 2.95 hours.

At its median distance that 1.7 billion mile (2.5 billion km), light takes 2.5 hrs to with Uranus indigenous Earth. As the world orbits the Sun, this time varies in between 2.38 hours and also 2.95 hours.

This also method that as soon as you look at Uranus native a telescope, you space looking at it as it looked at least 2.4 hours ago!

How lengthy Does it take it a Spaceship to travel to Uranus?

Only one spacecraft, Voyager 2, has visited Uranus so far. It took 9½ years to acquire there.

How long is a day on Uranus?

Uranus rotates with a rate of 2.59 km/s or 9,320 km/h. In ~ this speed, Uranus bring away just 17 hours and 14 minutes to finish a rotation on its axis — which is the size of a work on the planet.

Nailing the length of a day boils down to calculating a planet’s rotational speed, which is usually done by measure the rotational rate of the core. This is more difficult for ice cream giants due to the fact that they have a very little solid core engulfed through icy layers, do it challenging to gain accurate measurements.

However we understand is sidereal rotation, which steps its rotation v respect come the stars, offers us the figure above. Specifying a day by referral to the sun, i.e. The time between the sun reaching its highest allude in the sky and returning to it is complicated by the too much axial tilt of Uranus, which efficiently lies on its side.

The impact of this the Sun essentially only return to the same allude in thesky once per year. So, arguably, a job on Uranus is as long as 84 earth years!

How lengthy is a Year top top Uranus?

Uranus take away 84 earth years come orbit the Sun. While a day on Uranus is much shorter than that on Earth, its year is lot longer. This method that Uranus rotates faster than Earth but orbits the sunlight slower.

The further out a body is indigenous the Sun, the slower it orbits around it and the further it needs to travel to finish one circuit. This is why the giants at the sheet of our solar system take so lengthy to complete a solitary year. Simply see just how long Neptune takes come orbit the Sun, because that example.

Are There periods on Uranus?

Uranus is tilted by 97.77 degrees. That axial tilt linked with its an extensive year leads to excessive seasons top top the planet. Each season top top Uranus stretches for 21 planet years.

During summers and also winters, just one pole faces the sunlight while the other remains in finish darkness.

For spring and also fall, Uranus’ day and night move every 17 hours. This reasons rapid temperature changes and solid winds in its stormy atmosphere.


Uranus is the seventh planet from the Sun and also orbits the star in ~ 1.8 billion mile (2.9 exchange rate km). The orbit is practically circular with an eccentricity of just 0.04, which is why there isn’t a significant difference between its closest and also furthest ranges from the sunlight or Earth.

Voyager 2 is the only spacecraft that has actually visited Uranus for this reason far, and also it took 9½ year to get there.

A day on Uranus lasts just 17 hours but a year bring away 84 planet years come complete since Uranus orbits slowly around the Sun and has a substantial distance to cover.

This, combined with that axial tilt of 97 degrees, leads to too much seasons. Every pole deals with the sun for 21 years, bring about 21-year-long summers and also winters.
