Histogram of exoplanet host stars in distance bins of 5 pc (white with black outline) and the exoplanet host stars detected in the eRASSl survey (red) in the German eROSITA sky out to a distance of 200 pc. The detection fraction is high with about 70% out to 20 pc and then drops off rapidly. A small number of X-ray detections exists for planet host stars at larger distances.
