GA Sweeps: On Hold
As part of the WikiProject Good Articles, we're doing Sweeps to determine if the article should remain a Good article. I believe the article currently meets the majority of the criteria and should remain listed as a Good article. However, in reviewing the article, I have found there are several issues that need to be addressed. I have already made minor corrections to the article, but have included issues below that I believe need to be addressed for the article to remain a GA.

Needs inline citations:
 * 1) "The four inner or terrestrial planets have dense, rocky compositions, few or no moons, and no ring systems. They are composed largely of minerals with high melting points, such as the silicates which form their solid crusts and semi-liquid mantles, and metals such as iron and nickel, which form their cores."
 * 2) "...they probably formed by widespread volcanism early in mercurian history."
 * 3) "According to the data of the altimeters of the Pioneer, nearly 51% of the surface is found located within 500 metres (1,640 ft) of the median radius of 6,052 km (3760 mi); only 2% of the surface is located at greater elevations than 2 kilometres (1 mi) from the median radius."
 * 4) "Venus shows no evidence of active plate tectonics."
 * 5) "There is debatable evidence of active tectonics in the planet's distant past; however, events taking place since then (such as the plausible and generally accepted hypothesis that the Venusian lithosphere has thickened greatly over the course of several hundred million years) has made constraining the course of its geologic record difficult."
 * 6) "This research has led to the fairly well accepted hypothesis that Venus has undergone an essentially complete volcanic resurfacing at least once in its distant past, with the last event taking place approximately within the range of estimated surface ages."
 * 7) "In part, this is because Venus's dense atmosphere burns up smaller meteorites before they hit the surface. The Venera and Magellan data agree: there are very few impact craters with a diameter less than 30 kilometres (19 mi), and data from Magellan show an absence of any craters less than 2 kilometres (1 mi) in diameter."
 * 8) "Much of Venus' surface appears to have been shaped by volcanic activity."
 * 9) "Deserts cover about 20% of the total land area."
 * 10) "The geological history of Earth can be broadly classified into two periods namely:"
 * 11) "The geological history of Mars can be broadly classified into many epochs, but the following are the three major ones:"
 * 12) "It is made of thousands of rocky planetesimals from 1,000 kilometres (621 mi) to a few meters across."

Other issues:
 * 1) This isn't required for GA, but I tagged a few images to be moved over to Wikimedia Commons. If you have an account, consider moving the images over so that other language Wikipedias can use them as well.
 * 2) There are multiple external links, see if some can be removed. Check to see if some of the sites are duplicates or cover the same information. Consider using some of them for citing the above statements.
 * 3) There are various dead links in the articles that need to be fixed (see here). Use the Internet Archive to fix the links or replace them with new sources if possible.

This article was an interesting read with a handful of great free images. If the above issue is addressed, I believe the article can remain a GA. I will leave the article on hold for seven days, but if progress is being made and an extension is needed, one may be given. If no progress is made, the article may be delisted, which then can later be renominated at WP:GAN. I will contact the main contributors of the article and its related WikiProjects to ease the workload. If you have any questions, let me know on my talk page and I'll get back to you as soon as I can. --Happy editing! Nehrams2020 (talk • contrib) 02:50, 30 May 2009 (UTC)

GA Sweeps: Delisted
Unfortunately, since none of the issues were fixed, I have regrettably delisted the article according to the requirements of the GA criteria. If the remaining issues are fixed, consider renominating the article at WP:GAN. With a little work, especially with a collaboration among the multiple WikiProjects, it should have no problems getting back up to GA status. If you disagree with this review, you can seek an alternate opinion at Good article reassessment. If you have any questions let me know on my talk page and I'll get back to you as soon as I can. I have updated the article history to reflect this review. --Happy editing! Nehrams2020 (talk • contrib) 19:13, 5 June 2009 (UTC)
