Earth Warp/Homing in on Earth

Note: The placements of the labels at the start of the challenge are randomly-generated (so it may not look exactly like it does in the above screenshot).

At the beginning of this challenge, the text "Ellie is pleased. 'I can see your Solar System at last,' she says. 'I know the names of your planets, but could you tell me which is which?'" shall appear on the screen; once you've pushed Space to continue a picture of the Solar System that has nine wrongly-placed labels on it shall appear on the screen with the text "The planet labels are all in the wrong places." below it. Once you have pressed Space to continue for a second time, the text "You have to help Ellie get the planet labels in the right places." shall appear at the bottom of the screen - and once you've pressed Space to continue for a third time, the text "When a label is in the right place, the planet changes colour." will appear at the bottom of the screen. Once you have pressed Space to continue for a fourth time, the text "Choose a label with the space bar. Press the Return key to move it to the empty box. Press F0/F1 for help." (the key that you must press for help again depends on which version you're playing) will appear at the bottom of the screen; in B-Em, F0 is replicated by F1, but in !BeebIt, it is replicated by F10. Much like in that fourth challenge of Sky Hunter, the box in the bottom-left corner is merely a spare to move the first chosen label to - and for the first eight labels moved to the right places, the planets in question flash white, but if you should move a label that was in the right place back to a wrong one, the planet in question goes back to being magenta. Once all nine labels have been moved to the right places (after the Sun whose immovable label's already in the right place, the order's Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto), the last magenta planet will flash white, and the text "'Now all the planets have the right names,' says Jenny." will appear at the bottom of the screen; once you push Space to continue for a fifth time, the game shall proceed to its tenth challenge.
