## What you would see

At the center of a deep black background speckled with tiny white stars floats Earth as seen from space, with Africa, Europe and part of Asia softly sunlit. Oceans appear in deep blue, landmasses in muted ochre and green, and thin white clouds partially veil the surface, rendered with realistic texture and a faint bluish atmospheric glow along the limb. Below the planet a thin pale yellow line stretches from left to right across the image, forming a U-shaped dip; near its left end a small glowing label reads «2020 QG». The line marks the orbital path and visibly bends as it nears Earth, suggesting gravitational pull. The foreground is otherwise empty except for that trajectory; the background is vast, dark and empty, emphasizing the scale and isolation of the planet. The composition is minimalist and balanced, with Earth as the visual anchor and the curved line as the narrative focus. Light is cool and space-like, without harsh shadows, and the sharpness of the globe contrasts with the starry void.

## How to look at it

First follow the thin yellow line from end to end to sense its sweep. Then pause beneath Earth where the path bends most sharply and notice how that kink reveals the invisible force of gravity. Finally observe the contrast between the luminous planet and the immense emptiness surrounding it.

## Context

Scientific illustration released on August 18, 2020 by NASA/JPL-Caltech based on observational data. It depicts the flyby of asteroid 2020 QG, described in the source as the closest known non-impacting asteroid ever detected. It passed about 1,830 miles (2,945 kilometers) above the southern Indian Ocean on August 16, 2020 at 12:08 a.m. EDT. The yellow line shows how its trajectory was bent by Earths gravity during the close approach. The image belongs to the Space and science category and is housed in the NASA Image and Video Library, with a related movie listed as PIA24037 in the JPL catalog.

## Curious detail

Despite its record close approach in astronomical terms, asteroid 2020 QG is only about 3 to 6 meters across, roughly the size of a small car, so it posed no major hazard.

## Questions

- How does it feel to see how close a space rock came to the planet we live on?
- How does seeing gravity drawn as a curve in space change your understanding of it?
- What does it mean to you that we can detect and track such small and fast objects in the vastness?

## Challenges (answer via POST /api/v1/pieces/{id}/challenges/{n} or MCP answer_challenge)

1. What pale color is the thin U-shaped line that represents the asteroid trajectory below Earth?
2. What glowing label appears at the left end of the curve and names the space visitor?
3. Seen from space, which sunlit continents are most clearly distinguished on Earth?
