Venus orbits the Sun at an average distance of about 108 million kilometers (67 million miles), which is 0.72 AU.
Venus sits one step closer to the Sun than Earth, so its “distance from the Sun” is a classic Solar System fact people use for school, trivia, and quick scale checks. The clean number you’ll see most often is the average distance. Still, Venus doesn’t hold one fixed gap all year. Its orbit is close to circular, yet it’s still an ellipse, so the Sun–Venus distance slides a bit over time.
This page breaks down the numbers in kilometers, miles, and astronomical units (AU). It also explains what “average” means, why the distance changes, how long sunlight takes to get there, and how scientists measure it with such tight precision.
Venus Distance From The Sun In Miles And Kilometers
When people ask how far Venus is from the Sun, they usually mean Venus’ average orbital distance. NASA lists that average as about 108 million kilometers, which is about 67 million miles. In astronomy shorthand, that’s about 0.72 AU, where 1 AU is the mean distance between Earth and the Sun.
That “average” is a time-averaged value tied to the size of Venus’ orbit. It’s best thought of as the typical radius of Venus’ path around the Sun. If you could freeze Venus at random points across many orbits, the average of those Sun–Venus separations would land near that 108 million kilometer mark.
Why The Number Is Not One Fixed Distance
Venus travels on an ellipse. The ellipse is mild, so the swing is small compared with Mercury or Mars. Still, it means Venus reaches a closest point to the Sun (perihelion) and a farthest point (aphelion). Across that swing, the Sun–Venus gap changes by about 1.46 million kilometers, which is small next to 108 million kilometers, yet real.
Perihelion And Aphelion For Venus
Using standard orbital elements, Venus’ perihelion distance is about 107.48 million kilometers, and its aphelion distance is about 108.94 million kilometers. In miles, that’s about 66.8 million miles at perihelion and about 67.7 million miles at aphelion.
The takeaway is simple: most of the time, Venus stays near 108 million kilometers from the Sun. The orbit is so close to circular that the “closest” and “farthest” values don’t feel wildly different, but they’re still part of the real picture.
What “0.72 AU” Means In Plain Terms
Astronomers lean on AU because it keeps Solar System distances tidy. One AU is the mean Earth–Sun distance. Saying Venus is at 0.72 AU means Venus’ orbit is a bit under three quarters of Earth’s orbital size.
AU also helps you compare orbits without bouncing between miles and kilometers. If Earth’s average is 1 AU, Mercury is closer, Venus is next, then Earth, then Mars, and so on. That “one unit” yardstick keeps the order and spacing clear.
How Far From The Sun Is Venus? Distance In Numbers You Can Use
If you want a tight set of values to quote, use the average plus the closest and farthest points. The average answers the common question. The perihelion and aphelion numbers answer the “does it change?” follow-up.
NASA’s Venus facts page gives the headline average distance and a neat extra: from that distance, sunlight takes about six minutes to reach Venus. That’s a distance fact turned into a time fact, and it helps the scale click. NASA’s Venus facts page states both the average distance and the light travel time.
What Changes During A Venus Year
Venus completes one trip around the Sun in about 224.7 Earth days. Over that time, it slides from perihelion to aphelion and back, tracing that slightly oval path. The change in distance is driven by the orbit’s eccentricity, which is tiny for Venus, near 0.0068.
A low eccentricity means the orbit is close to a circle. So, Venus doesn’t get dramatically closer to the Sun in one season and dramatically farther in another. The spacing stays in a narrow band around the average.

Why Venus Is Not Hot Just Because It’s Closer
Venus is closer to the Sun than Earth, so it receives more solar energy per square meter. That’s real. Still, distance alone doesn’t explain Venus’ oven-like surface. The bigger driver is its dense carbon-dioxide atmosphere and the way it traps heat.
This is why “closer to the Sun” is not a full answer for “why is Venus hotter than Mercury?” Mercury sits closer still, yet it lacks a thick heat-trapping atmosphere. Mercury’s temperature swings hard between day and night. Venus stays scorching both day and night because its atmosphere keeps heat from escaping.
Solar Energy Drops With The Square Of Distance
Sunlight spreads out as it travels. Double the distance and the same energy is spread over four times the area. Venus at 0.72 AU receives roughly 1 / (0.72²) times Earth’s solar energy, which is close to 1.9 times Earth’s. That’s a useful scale fact, but it still doesn’t get you to Venus’ surface conditions by itself.
How Scientists Measure The Distance So Well
Distances in the Solar System are not guessed. They’re measured and cross-checked with several methods.
Radar Ranging
For inner planets, radar is a workhorse method. Scientists transmit a radio pulse, let it bounce off a planet, then measure the round-trip time. With the speed of light known, that time converts into a distance along the line of sight at that moment. Repeating those measurements across time helps lock in orbital parameters.
Tracking Spacecraft
Spacecraft telemetry adds another layer. When a mission passes Venus or orbits it, the spacecraft’s radio signal can be tracked with tight precision. Tiny Doppler shifts and timing measurements help refine Venus’ position and the geometry of its orbit.
Orbital Models And Ephemerides
Modern planetary positions are packaged in ephemerides: tables and models that predict where a body will be at a given time. They fold in gravity from other planets, relativistic corrections, and decades of observations. Venus’ low-eccentricity orbit makes its Sun distance easy to pin down with small uncertainty.
How Venus’ Distance Compares With Other Planets
Distance facts are easier to hold onto when you see them side by side. Venus is the second planet from the Sun, sitting between Mercury and Earth. NASA’s main Venus overview puts Venus in that spot and summarizes the planet’s place in the Solar System. NASA’s Venus overview is a good official reference for the big-picture context.

| Mercury | 0.39 | 57.9 |
| Venus | 0.72 | 108 |
| Earth | 1.00 | 149.6 |

Distance Facts People Mix Up With Venus
Venus is close to Earth at times, and far from Earth at other times, so people sometimes swap “distance from the Sun” with “distance from Earth.” Those are different questions. The Sun–Venus distance stays near 108 million kilometers. The Earth–Venus distance changes a lot because both planets are moving on their own orbits.
Closest Approach To Earth Is A Separate Number
At certain alignments, Venus can pass tens of millions of kilometers from Earth. That’s still far in human terms, but it’s much smaller than the Sun–Venus distance. When Venus is near inferior conjunction (between Earth and the Sun), it can be much closer to us. When it’s on the far side of the Sun (at conjunction on the far side), it’s far from us. The Sun distance does not follow that same pattern.
Light Travel Time: A Clean Way To Feel The Scale
Distance numbers can feel abstract. Time helps. At Venus’ average Sun distance, sunlight takes about six minutes to arrive.
That means when you see sunlight reflecting off Venus in the evening or morning sky, the light left the Sun minutes earlier, hit Venus, then continued on toward Earth. In that sense, you’re watching a brief, real-time relay: Sun to planet to your eyes.
Does Venus’ Distance Affect What We See From Earth?
It affects Venus’ brightness and apparent size far more than it affects the Sun’s pull on Venus. When Venus is closer to Earth, it looks bigger. When it’s farther, it looks smaller. But Venus also goes through phases like the Moon, since we see varying amounts of its day side. The brightest Venus is not always the closest Venus, because the visible illuminated fraction matters.
Venus’ distance from the Sun does affect the sunlight Venus receives, which affects its cloud-top brightness and atmospheric dynamics. Yet the small perihelion-to-aphelion swing means these changes are subtle compared with the huge effects of its atmosphere and rotation pattern.
How To Explain The Answer In One Sentence
If you need a one-line explanation for a class answer, stick with the average distance and the AU value. Then add a second sentence for perihelion and aphelion if your teacher asks for detail.
- One-sentence answer: Venus orbits the Sun at about 108 million kilometers (67 million miles), or 0.72 AU.
- Detail add-on: Venus ranges from about 107.48 to 108.94 million kilometers from the Sun across its orbit.
