In practice, however, Jupiter's orbit is very close to circular; its distance from the Sun only varies by about 10.1% between perihelion and aphelion. This means that the difference in the amount of heat and light it receives from the Sun between aphelion and perihelion is extremely small.
Jupiter's distance from the Sun doesn't affect its appearance. From Ashburn (click to change), at the moment of aphelion it will be visible in the morning sky, becoming accessible at around 22:48, when it rises 7° above your eastern horizon. It will then reach its highest point in the sky at 03:46, 43° above your southern horizon. It will be lost to dawn twilight at around 06:39, 28° above your south-western horizon.
The position of Jupiter at the moment it passes aphelion will be:
