Planet Uranus and the asteroid 4 Vesta - spectral comparison

Comparison of the spectra of the gas planet Uranus, the asteroid 4 Vesta, and the star 20 Leonis Minoris (20 LMi).

The Sun is an average yellow-white dwarf star of spectral class G2V. Given that 4 Vesta reflects the light of the Sun nearly perfectly, 4 Vesta displays a typical G2V class spectrum. The spectrum of the star 20 LMi, an almost identical twin of the Sun of spectral class G3V, is shown for comparison, and its spectrum is seen to overlap nearly perfectly with that of 4 Vesta.

The light from Uranus is also reflected sunlight, however, in the spectrum of Uranus there are additional strong, broad absorption lines due to the methane, that is abundant in Uranus' lower atmosphere.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
