Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Review Description
The Moon's origin is a long-debated scientific question, and its unique characteristics have led to the widespread acceptance of the giant impact hypothesis as the dominant theory explaining how the Moon formed. According to the canonical impact model, an impactor about the size of Mars collided with Earth, leading to the formation of a debris disk primarily composed of material from the impactor, within which the Moon subsequently formed. However, the canonical impact model faces an important challenge in accounting for the remarkably similar isotopic anomalies across various isotope systems observed in both Earth and the Moon, referred to as the "isotope crisis". To address this quandary, a range of new computational models depicting the giant impact has been proposed. Nevertheless, the inquiry into the Moon's origin is still far from a conclusive resolution. Consequently, acquiring additional experimental and exploratory data becomes imperative. Furthermore, delving deeper into the limitations and mechanisms of numerical models is crucial, offering the potential for an enhanced understanding of Earth and Moon's evolution. This paper provides an extensive evaluation of the primary computational models associated with the giant impact theory. It explores the advancements made in research related to this theory and analyzes its merits and limitations.
