Wie kann die Entfernung der Voyager von der Sonne weniger als 2 AE betragen als von der Erde, wenn die Erde nie weiter als 1 AE von der Sonne entfernt fliegt? Vielleicht verstehe ich etwas nicht und die Antwort liegt auf der Hand, oder handelt es sich um einen Fehler auf der NASA-Website?

Earth rotates around the sun. At that moment, earth may be behind the sun. Earth – Sun – Voyager.
According to this it’s a bug: https://www.reddit.com/r/nasa/s/hSIUcdJqb9
The statement that earth is 1 AU from the sun is an average distance. The Aphelion and Perihelion of Earth’s orbit are both closer and further than 1 AU. Earth’s orbit is near circular but not perfectly circular.
Also, yes… it is a known bug.
Edit: apparently I’m dumb, but I won’t hide my stupidity
Picture the earth as a spot on a record and the sun in the center. You’re imagining Voyager moving out towards the edge of the record. But really it’s moving up towards the ceiling

Boy that title is rough. The distance difference should be less than 2 au. The problem is that it’s significantly more than 1 au for Voyager 1.
„How can Voyager 1 be 2 au further from Earth than from the sun?“
Isn’t the Earth and sun constantly moving forward as well as rotating?
Is Earth kind of following voyager’s path, would that keep it close to us?
Could we drop a stationary satellite where the earth is now, and have it sync our earth’s orbit on the opposite side of our orbit?
If it’s a straight line from the sun, to the Earth, to Voyager. And I jump off the Earth and stop right here. In 182.5 days(ish) the Earth is going to be on the other side of the sun and it’s going to be two AU away from me. So it’s going to be earth, sun, me, Voyager.
So from the Earth to the sun is 1 AU, sun to me is 1 AU, and then a really long distance to Voyager. But the Earth will be 2 AU farther than where I got out.
At the 91.25-ish day point, you could have a spot where the Earth and sun are the same distance to Voyager.
What side of the sun is earth on?
The Earth is orbiting the Sun, but the Voyagers are moving away from both the Sun and Earth, so as Earth orbits the Sun, there’s a time in the year where Earth is closest to either Voyager, three months later, the Sun and Earth will be the same distance from Voyager, and another three months after that, it will be at it’s furthest from Voyager since it’s on the other side of the Sun. The difference between those two points, six months apart, is 2AU. The Voyagers are moving in different directions, and aren’t moving parallel to the Earth’s orbit, but my explanation should help you understand the concept.
