How far is "close"?
Same gap, ranked against places you have heard of, on a log scale because the Sun is awkwardly far away.
How big is it, really?
NASA only estimates the width, so we show the biggest guess. Log scale again. Everest is just there to make everything else look reasonable.
How fast is it going?
Speed relative to Earth at closest approach. The International Space Station is the fastest thing most of us will ever stand under. This lot would lap it.
If it hit (it will not)
Rough impact energy at the biggest size estimate, assuming solid rock, in tonnes, kilotons and megatons of TNT, which is how everyone who has to do this maths measures it. Treat it as a ballpark. The point stands: no impact is scheduled.
Where it actually lives
A top-down view of the orbit, to scale, with Earth's and Mars's orbits for company. The tilt of the orbit is ignored, so treat the shape as right and the exact position as roughly right. The Sun is the orange dot in the middle.
- Orbit class
- APOApollo: crosses Earth's orbit, but spends most of its time further out than us. The most common troublemaker type.
- Year length
- 1.75 Earth years (638 days)One lap of the Sun. Your commute is shorter, and so is your patience.
- Eccentricity
- 0.572How squashed the orbit is. 0 is a perfect circle, 1 is "leaving". Very stretched. This rock commutes the long way round.
- Tilt
- 12.6°The angle of its orbit against the flat plane the planets share. Slightly tipsy.
- Closest to the Sun
- 0.62 AU93 million km. One AU is the distance from Earth to the Sun.
- Furthest from the Sun
- 2.28 AU341 million km. Out past Mars.
- Closest orbit-to-orbit gap
- 0.006 AUIf you only compare the two orbits, not where the planets are, they come within 2 lunar distances. The rock is rarely there at the same time as us, which is the entire reason we are still here.
- Observations used
- 100NASA has measured this one 100 times. It has been stalked thoroughly.
- Watched for
- 24 days2019-11-01 to 2019-11-25. Not long, so the orbit is still being refined and the rock is still a bit of a stranger.
- Orbit uncertainty
- 6 out of 90 means we know exactly where it is going. 9 means a shrug. Lower is better.
Is it actually hazardous?
This one fails at least one test, so it is not on the list. It is comfortably, boringly harmless.
Not on NASA's Sentry impact-risk watch list. No further action, no thoughts, head empty.
Its history with us
Every known pass this rock makes, 1900 to 2200. Dim dots are the past, green dots are still to come, the big orange ring is this one. The dashed line is the Moon's distance, so anything below it is closer than the Moon. Almost nothing is.

By the numbers
- Estimated mass
- 467,503 tonnes to 5.2 million tonnesVolume of a sphere at NASA's smallest and largest width estimates, times 3,000 kg per cubic metre (typical rock). Real shapes are lumpier, so treat it as a ballpark.
- Swimming pools of rock
- 264 Olympic poolsSphere volume at the middle width estimate, divided by 2,500 cubic metres per Olympic pool.
- Impact energy, if it hit
- 22 megatons to 246 megatonsHalf mass times speed squared, at the small and large width estimates, converted to TNT (1 kiloton is 4.184 trillion joules). A rock this far away is not going to do this.
- Speed against escape velocity
- 1.8 timesIts speed relative to Earth, divided by the 11.186 km/s needed to leave Earth's gravity. It is travelling a lot faster than we can throw things.
- Speed against Earth in orbit
- 0.67 timesDivided by Earth's own orbital speed of 29.78 km/s around the Sun.
- Time to cross the UK
- 48.9 secondsLand's End to John o' Groats is about 970 km in a straight line. Divided by its speed.
- Time to fly the miss distance
- 5.2 daysThe miss distance divided by its speed. This is how long it needs to cover a gap of that size, which is a measure of how near or far the pass is.
- Light takes to cross the gap
- 30.0 secondsMiss distance divided by the speed of light.
- Width from brightness alone
- 67 to 149 mAstronomers estimate size from how bright an asteroid is (H 23.0) and how reflective it is. A shiny rock (albedo 0.25) is smaller than a dark one (0.05) for the same brightness. NASA's own estimate above uses the same idea.
- Laps of the Sun since first spotted
- 0.024 days of observation divided by its 638-day year.
- Known close approaches, 1900 to 2200
- 280 inside the Moon's orbit and 2 within ten lunar distances.
- Closest pass in that period
- 4.39 lunar distancesOn 23rd November 1958.
- Next visit after this one
- 28th May 2032At 17.7 lunar distances. Closer than this time.
- Average gap between visits
- 8.6 yearsThe span of the record divided by the number of gaps between approaches.
- Rank by size
- 21 of 42Among every asteroid this site has tracked, biggest first.
- Rank by closeness
- 4 of 42Among every asteroid this site has tracked, using each one's most recent pass, closest first.
- Rank by speed
- 6 of 42Among every asteroid this site has tracked, fastest first.
How reliable are these?
Width, speed, miss distance and orbit come straight from NASA. Mass, energy, volume and the rankings are our own arithmetic on top, and the assumptions are written beside each one. NASA publishes a range for width because nobody has seen most of these rocks up close, so wherever we show one number it uses the biggest estimate and says so.
Will asteroid 2019 VF1 hit Earth? Questions answered
Will asteroid 2019 VF1 hit Earth?
No. 2019 VF1 passes Earth on 20th November 2026 at 23.4 lunar distances (8,981,854 km), which is 23.4 times the distance to the Moon. It is not on NASA's potentially hazardous list. It is not on NASA's Sentry impact-risk watch list.
How big is asteroid 2019 VF1?
NASA estimates it is between 67 m and 149 m wide, which at the top end is about 1.4 football pitches long. Nobody has seen it up close, so the width is an estimate from its brightness.
How fast is asteroid 2019 VF1 travelling?
19.8 km/s relative to Earth at closest approach, about 71,400 km/h (44,366 mph). That is 2.6 times the speed of the International Space Station.
Is 2019 VF1 a potentially hazardous asteroid?
No. NASA gives the label to asteroids whose orbit comes within 0.05 astronomical units of Earth's (about 7.5 million km) and which are bigger than roughly 140 m. 2019 VF1 has an absolute magnitude of 23.0 and its orbit comes within 0.006 AU of Earth's.
When is asteroid 2019 VF1's next close approach?
After this pass, the next one in NASA's record is on 20th November 2026, at 23.4 lunar distances.
Unhelpful facts
- About 1.4 football pitches long. Still no better than a mid-table side.
- At its speed it covers a gap the size of its miss distance in 5.2 days. A group chat would still be picking a restaurant.
- About 426 wheels of Gouda across. A brave scientist would call that a dairy event.
- That is 1,478 times the speed limit on a 30 zone. Nobody has fined it yet.
- A jet would have to circle Earth 224 times to cover the gap. Baggage still lost.
- Line up 24 elephants to match its width. The elephants would like to be consulted first.
- At this speed it covers the distance to the Moon in 5.4 hours. Your train replacement bus takes longer.
- In the 5.2 days it takes to fly a gap that size, you could drink 377 cups of tea. Most would go cold.
- A UK train would take 10.3 years to cross the same gap, plus delays "due to a train being late".
- 6.00% of the way to the Sun. Nobody is cancelling summer.
- Flying a gap that size takes it 5.2 days, which is 377 twenty-minute naps. Recommended.
- 419 large pizzas wide. Delivery in thirty minutes or it is free (it will not be free).
