Sonda Parker in acest moment se afla nu la 24 mil km fata de Soare ci la 3.83 mil km .
Ea a traversat o zona in care de la 7 mil de km exista foarte putin praf stelar (particule legate carbon- hidrogen care sunt materia prima pentru  formarea vietii) si foarte putin praf cosmic,
Aceasta zona libera de praf a inceput de la 7 mil de km si tine pana la aprox. 2-3 mil de km.

,,"This dust-free zone was predicted decades ago, but has never been seen before," said Russ Howard, principal investigator for the WISPR suite &#8212; short for Wide-field Imager for Solar Probe &#8212; at the Naval Research Laboratory in Washington, D.C. "We are now seeing what's happening to the dust near the Sun."
