This illustration exhibits the Parker Photo voltaic Probe approaching perihelion: its closest strategy to the Solar. It’ll obtain its closest strategy ever on December 24, 2024, coming inside simply 4.43 photo voltaic diameters of the Solar’s photosphere.

The Parker Photo voltaic Probe is about to endure its seventh encounter with Venus on its journey in direction of the Solar. Right here’s how briskly it’ll go.
On September 30, 2024, the Parker Photo voltaic Probe reached its twenty first perihelion: its closest strategy to the Solar.
The science questions which can be being answered by the Parker Photo voltaic Probe are elementary to understanding the Solar, its corona, and the phenomenon of area climate. By the top of its mission, the Parker Photo voltaic Probe could have set a lot of information and scientific firsts, together with changing into the closest and quickest spacecraft ever with respect to the Solar.

Presently, perihelion is simply 7.87 million km (4.89 million miles) from the Solar’s floor.
This picture and plot exhibits the Parker Photo voltaic Probe’s path and distance, with respect to the Solar, from its August 12, 2018 launch till its twenty first perihelion, which it reached on September 30, 2024. (Credit score: NASA/JHU/APL)
Its novel warmth protect permits science operations underneath these excessive circumstances.
The warmth protect for the Parker Photo voltaic Probe, seen because the topmost construction right here with a white alumina coating on the outer floor, is totally mandatory for shielding the important devices inside from the in any other case catastrophic warmth from the Solar. As soon as the warmth protect fails, the whole probe is destined to fail inside seconds. (Credit score: NASA/Johns Hopkins APL/Ed Whitman)
From closest strategy, the Solar seems 28 instances bigger than terrestrial views.
